Failure of Unidirectional Composites under Combined Loads.
Abstract
The mechanisms of failure of unidirectional composites were studied under combined stresses. The effects of fiber and matrix constitutive behavior, statistics of fiber strength, and fiber-matrix interface characteristics on composite strength were studied. The salient features of lamina strength under axial tension/axial shear were determined. Examples are given for boron/epoxy and glass/epoxy. An exploratory axial shear/transverse tension/transverse shear using upper bound limit analysis techniques was performed as a means of estimating the effects of interlaminar stresses on composite failure.
