IMPACT OF A BAR WITH LUMPED MASS AT RIGID BARRIER

Abstract

A stress wave propagation dynamic problem due to impact of elastic bar at a rigid barrier is considered. It is presumed, that the bar is equipped with a dot mass at free end and «sticks» to rigid barrier after impact. The problem is solved with Laplace transformation.
