Attenuation of Longitudinal Elastoplastic Pulses
In this chapter, we discuss (in tutorial fashion) the attenuation of a uniaxial-strain pulse propagating in an elastoplastic solid. This is an old and familiar problem, but its solution seems not to have been presented in the detail required to properly describe the many and varied wave interactions that produce the propagated waveform and lead to attenuation of the pulse. These problems are usually solved by numerical means, often in the context of considerably more comprehensive theories than the one used here. However, some interesting phenomena are easily overlooked when examining the numerical results.
