The applicability of instrumented falling weight impact techniques in characterizing mechanichally thermoplastic foams at relatively high strain rates is presented. In order to try simulating impact loading of foams against sharp elements, an instrumented dart having a hemispherical headstock was employed in the test. Failure strength and toughness values were obtained from high-energy impact experiments, and the elastic modulus could be measured from both flexed plate and indentation low-energy impact tests. The result indicate a dependence of the failure strength, toughness, and the elastic modulus on the foam density, the foaming process, and the chemical composition. This influence was found to be similar to that of pure nonfoamed materials and also to that observed from low-rate compression tests. The results also indicate that the indentation low-energy impact tests were more accurate in obtaining right values of the elastic modulus than the flexed plate low-energy impact tests usually used to characterize rigid plastics. The foam indentation observed with this test configuration contributes to obtaining erroneous values of the elastic modulus if only a simple flexural analysis of plates is applied.

Traditionally, impact tests have been employed to measure the ability of a sample or a finished part to absorb a shock or impact. Falling weight impact tests stand out among the different types of impact tests because the simply supported or fixed (clamped) sample receives the collision of a mass falling from determined height. These tests have advantage of multiaxiality and the possibility of working with finished articles, if they are properly fixed.
The noninstrumented (analogic) impact tests give neither qualitative information about the energy required for the fracture initiation nor the information about the mechanical behavior of the material. These tests give only statistical plots as a relationship between the probability of failure or survival of the sample according the strictness of the test.

For equations with one main condition
(Those linear), you have permission
To take your solutions,
With firm resolutions,
And add them in superposition. *
Let’s say a little more about the solution in eq. (3.2). If a is negative, then let’s define a = -cu2, where cu is a real number. The solution now becomes x(t) = Aeiojt + Be-iojt. Using eie = cos 6 + i sin 0, this can be written in terms of trig functions, if desired. Various ways of writing the solution are:
x(t) = Ae^' + Be-™'
x(t) = C cos cut+ D sin cut,
x(t) = Ecos(uut + 4>1),
x(t) = Fsin(cut + 4>2). (3.3)
The various constants here are related to each other. For example, C = E cos f1 and D = -E sin f1, which follow from the cosine sum formula. Note that there are two free parameters in each of the above expressions for x(t). These parameters are determined from the initial conditions (say, the position and speed at t = 0). Depending on the specifics of a given problem, one of the above forms will work better than the others.
If a is positive, then let’s define a = cu2, where cu is a real number. The solution in eq. (3.2) now becomes x(t) = Aeut + Be-"*. Using ee = cosh(9 + sinh<9,>
x(t) = Ae^ + Be-^
x(t) = C cosh cut+ Dsinh cut,
x(t) = Ecosh(cut + 4>1),
x(t) = Fsinh(cut + 4>2). (3.4)
Again, the various constants are related to each other. If you are unfamiliar with the hyperbolic trig functions, a few facts are listed in Appendix A.
Remarks: Although the solution in eq. (3.2) is completely correct for both signs of a, it is generally more illuminating to write the negative-a solutions in either the trig forms or the e±iujt exponential form where the i’s are explicit.
As in the first example above, you may be concerned that although we have found two solutions to the equation, we might have missed others. But the general theory of differential equations says that our second-order linear equation has only two independent solutions. Therefore, having found two independent solutions, we know that we’ve found them all. *
The usefulness of this method of guessing exponential solutions cannot be overemphasized. It may seem somewhat restrictive, but it works. The examples in the remainder of this chapter should convince you of this.
This is our method, essential,
For equations we solve, differential.
It gets the job done,
And it’s even quite fun.
We just try a routine exponential.

Oscilations part 1
Linear differential equations
A linear differential equation is one in which x and its time derivatives enter only through their first powers. An example is 3x¨+7x˙ +x = 0. An example of a nonlinear differential equation is 3x¨ + 7x˙2 + x = 0.
If the right-hand side of the equation is zero, then we use the term homogeneous differential equation. If the right-hand side is some function of t, as in the case of 3x¨ - 4x˙ = 9t2 - 5, then we use the term inhomogeneous differential equation. The goal of this chapter is to learn how to solve these two types of equations. Linear differential equations come up again and again in physics, so we had better find a systematic method of solving them.
The techniques that we will use are best learned through examples, so let’s solve a few differential equations, starting with some simple ones. Throughout this chapter, x will be understood to be a function of t. Hence, a dot will denote time differentiation.
Example 1 (x˙ = ax): This is a very simple differential equation. There are two ways (at least) to solve it.
First method: Separate variables to obtain dx/x = adt, and then integrate to obtain lnx = at + c. Exponentiate to obtain
x = Aeat, (3.1)
where A = ec is a constant factor. A is determined by the value of x at, say, t = 0.
Second method: Guess an exponential solution, that is, one of the form x = Aeat. Substitution into x = ax immediately gives a = a. Therefore, the solution is x = Aeat. Note that we can’t solve for A, due to the fact that our differential equation is homogeneous and linear in x (translation: A cancels out). A is determined from the initial condition.
This method may seem a bit silly, and somewhat cheap. But as we will see below, guessing these exponential functions (or sums of them) is actually the most general thing we can try, so the method is indeed quite general.
Remark: Using this method, you may be concerned that although we have found one solution, we might have missed another one. But the general theory of differential equations says that a first-order linear equation has only one independent solution (we’ll just accept this fact here). So if we find one solution, then we know that we’ve found the whole thing. *
Example 2 (x = ax): If a is negative, then this equation describes the oscillatory motion of, say, a spring. If a is positive, then it describes exponentially growing or decaying motion. There are two ways (at least) to solve this equation.
First method: We can use the separation-of-variables method of Section 2.3 here, because our system is one in which the force depends on only the position x. But this method is rather cumbersome, as you found if you did Exercise 2.10 or 2.11. It will certainly work, but in the case where our equation is a linear function of x, there is a much simpler method:
Second method: As in the first example above, we can guess a solution of the form x(t) = Aeat and then find out what a must be. Again, we can’t solve for A, because it cancels out. Plugging Aeat into i¨ = ax gives a = ±^. We have therefore found two solutions. The most general solution is an arbitrary linear combination of these,
x(t) = Ae^1 + Be-^\ (3.2)
as you can quickly check. A and B are determined from the initial conditions.
Very Important Remark: The fact that the sum of two different solutions is again a solution to our equation is a monumentally important property of linear differential equations. This property does not hold for nonlinear differential equations, for example x2 = x, because the act of squaring after adding the two solutions produces a cross term which destroys the equality, as you should check.
This property is called the principle of superposition. That is, superimposing two solutions yields another solution. This quality makes theories in physics that are governed by linear equations much easier to deal with than those that are governed by nonlinear ones. General Relativity, for example, is permeated with nonlinear equations, and solutions to most General Relativity systems are extremely difficult to come by.

More Thoughts on the Decline of News Ombuds
Dvorkin points to research that supports the need for an ombuds. One study by the Guardian in London showed that the cost of litigation drops by as much as 30% when there is an ombuds on staff. Other studies have shown that having an ombuds increases credibility and community respect for the newspaper or broadcaster and that an ombuds is good for internal newsroom morale. Dvorkin also notes that support for news ombuds is coming from non-news ombuds, whose ranks are growing fast in academia, government and not-for-profits. (Salon.com.)

U Washington Faces Lawsuit Despite Mediation by Ombuds
The plaintiff was a former equipment manager for the football team. She claims that a consensual sexual relationship with Roc Alexander became increasingly abusive and culminated in an assault. Months later, the plaintiff went to the UW athletic department and reported what had happened. She was advised to step down from her position with the team to avoid harassment by any of the players. Refusing, she agreed to attend a three-hour mediation overseen by the University Ombuds, where she asked that Alexander be suspended from the football team. The plaintiff alleged that at the conclusion of the mediation, the Ombuds "decided that Alexander would undergo counseling and perform community service." The plaintiff also claimed that, although the UW has a program for sexual-assault victims, the Ombuds did not refer her to that program.
In interviews with Seattle Times, the plaintiff said the mediation was "totally biased" against her. "I think that's the thing that has stuck with me -- how [the mediation] was run and the lack of outcome." The current UW Ombuds said Monday that the UW no longer uses mediation in cases of alleged sexual assault. (S.S. v. Alexander, No. 58335-2 (Wash. Ct. App., Feb. 11, 2008); Seattle Times; Seattle Post-Intelligencer.)
The procedural posture of the case dictated that the appeals court assume the plaintiff's version of facts to be true in order to address the legal sufficiency of her claims. These facts will therefore be challenged and tested in the trial court. Nonetheless, this case is sure to raise concern among ombuds and mediators. Here are the
- The UW Ombuds has a mandate to assist in protecting students' rights, is charged with the authority to receive complaints from students, and may recommend redress by the University President when the Ombuds has been unable to resolve the matter;
- The decision to conduct the mediation was made by the Ombuds, the Athletic Director, and the Assistant Athletic Director;
- The Ombuds did not disclose on-campus or off-campus resources to the plaintiff;
- The Ombuds revealed details of her conversation with Alexander to the plaintiff before the mediation;
- Mediation communications by the parties and the Ombuds/mediator came in to evidence (with no consideration of Washington's statutory mediation privilege);
- The mediation was resolved by a decision by the Ombuds/mediator and the Assistant Athletic Director;
- After the mediation, the Ombuds/mediator dictated a written statement for the plaintiff, acknowledging the matter was closed; and
- The Ombuds was an "appropriate official" for purposes of notice under Title IX.
Ombuds can take some solace in the apparent fact that the UW program does not conform to IOA Standards of Practice and thus is not an Organizational Ombuds per se. In particular, the mandate for the UW Ombuds specifically prevents it from being neutral, impartial, and informal. Moreover, the UW Ombuds disclosed communications that Organizational Ombuds would consider confidential. However, since the court did not recognize these distinctions, this is small comfort.

California Appellate Court Details Intervention by UCI Ombuds
“meant to revisit the decision in the interest of procedural fairness [regarding] first-year review and not the substance of the discussion leading to the outcome during the first-year review.” Essentially, the Ombudsman made clear he was questioning the process, and was not attempting to second-guess the academic decisions of the faculty. Many of the questions were focused on whether students were being given adequate notice of what was expected, and given the earliest possible notice of deficiencies.
The History Department renewed its recommendation that the student be awarded a terminal master's degree, but offered him a second chance on certain conditions. Ultimately however, the student was terminated from the University and filed suit. The appellate court upheld summary judgment for UCI in part and returned a few remaining claims to the trial court. Subsequently, the case settled. (Lachtman v. Regents of Univ. of Cal., 158 Cal. App. 4th 187, 70 Cal. Rptr. 3d 147, 2007 Cal. App. LEXIS 2063 (Cal. App. 4th Dist. 2007).)
As a published decision, this case may be cited as precedent by California courts. Although the court did not address the propriety and scope of the Ombuds' limited involvement, readers may question how the Ombuds’ email came into evidence.

Daniel J. Metcalfe, who ran the DOJ Office of Information and Privacy before retiring voiced his concern. “Ironically, this is so transparent: OMB and Justice seek to avoid complying with this FOIA amendment by instead merely proposing its alteration, and through an appropriations process that of course won’t conclude until near the end of the year, if even by then,” Metcalfe said. “Meanwhile, existing law is flouted, a terrible example is set for FOIA implementation, and ‘the clock is run out’ by this administration. Congress should see through this and not tolerate it.” (Austin American-Statesman; GovernmentExecutive.com.)
