Analytical and experimental studies of graphite-epoxy and boron-epoxy angle-ply laminates in compression

Creators

Description

The applicability and adequacy of several computer techniques in predicting satisfactorily the nonlinear/inelastic response of angle-ply laminates were evaluated. The analytical predictions were correlated with the results of a test program on the inelastic response under axial compression of a large variety of graphite-epoxy and boron-epoxy angle-ply laminates. These comparison studies indicate that neither of the above-mentioned analyses can satisfactorily predict either the mode of response or the ultimate stress value corresponding to a particular angle-ply laminate configuration. Consequently, also the simple failure mechanisms assumed in the analytical models were not verified
