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.
