Crack Growth in Unidirectional Composites Under Repeated Loadings

Abstract

A phenomenological description of the slow growth of longitudinally oriented cracks in an orthotropic plate is explored. Detail microscopic mode of crack extension is dominated by crack skipping around the fibers. This crack skipping contributes to the increase of resistance to subsequent crack growth. Mathematical models are used to relate experimental results of crack growth under repeated loadings.
