Large Amplitude Waves in Bounded and Stratified Media.
Abstract
The general aim of the research carried out on this contract has been to develop mathematical techniques that can be used to analyze the dynamic deformations that result from the interaction of large amplitude waves in elastic-plastic materials. Part i of the study, studied the deformation that is produced when a large amplitude, but shockless, pulse traveling through an elastic material arrives at an interface with another elastic material. The pulse propagates in a direction normal to the interface. First, the ideas of nonlinear impedance, reflection coefficient and transmission coefficient for such an interface were introduced. These were then used to determine the amplitudes of the reflected and transmitted pulses in terms of that of the incident pulse. In Part II of this study a more detailed account was given of the deformation produced in an elastic slab when one boundary is impulsively loaded while the other radiates energy to an adjacent material.
