A Comparison of the Williams Modal Expansion with the Classical Modal Expansion for Shock Analysis Computations.

Abstract

A cantilever beam is subjected to uniformly distributed, smooth pulses of varying durations. The solution is obtained by Williams' method and the Classical Modal Expansion method. Approximations to the peak response are computed by the Biot and the Fung and Barton techniques. These techniques which were originally devised in conjunction with the Classical Modal Expansion method, are found not to be applicable when Williams' method is employed.
