Transient Response of a Cantilevered Plate to Impact Using Holographic Interferometry and Finite Element Techniques.

Abstract

This report covers work carried out at AFAPL's Turbo Structures Research Laboratory (TSRL) on the transient structural response of an isotropic cantilevered plate subjected to normal impact by a ballistic pendulum. The program was a combined experimental/analytical effort. The experimental portion utilized a pulsed ruby laser to obtain holographic interferograms of the plate's deformation following impact. The analytical portion of the work consisted of mathematically modelling the plate using finite element techniques and studying the model's response to impact using the general purpose finite element program, NASTRAN.
