Higher Modal Dynamic Plastic Behavior of Beams Loaded Impulsively.

Abstract

The higher modal dynamic plastic response of fully clamped beams has been examined using various rigid perfectly plastic theoretical procedures and a numerical elastic-plastic computer code. The theoretical predictions agree reasonably well with the corresponding experimental values on strain rate insensitive beams which were subjected to first and second modal initial velocity distributions. However, all the experimental results for the third mode case lie below the various theoretical methods and numerical results, the reason for which is possibly due to the neglect of transverse shear effects.
