Measurement of Displacement Around Holes in Composite Plates Subjected to Quasi-Static Compression.

Abstract

This study is part of a continuing exploration of the structural behavior of fiber-reinforced composite materials by NASA (Langley). The dual purposes of the present research are to (1) develop a whole-field, high sensitivity optical technique to measure load-induced changes of thickness of composite plates, and (2) measure changes of thickness of three composite plates, each with a central hole of different prescribed size, as a function of applied compressive loads. The specimens were graphite-epoxy plates.
