Influence of Duration of Impact on Damage to Some Elastic Systems

Abstract

In order to estimate the effects on mounted apparatus of shock or impact loading, simplified elastic systems may be taken to represent the actual structures, so as to make possible mathematical analysis. One such simplified system is a simple mass-spring system attached to the frame or table which is subjected to shock. An analysis of the probable damage done to this system by a drop test type of impact has been made previously. Another system is a cantilever beam, whose clamped end is subjected to a specified transverse impact. This system differs fundamentally from the simple mass-spring system in that its flexibility and mass are distributed, rather than lumped.
