Description
Abstract:Composite failure is predicted quantitatively for specific fiber reinforced specimens containing stress concentrations around the periphery of a circular hole in an orthotropic plate. The maximum distortional energy around the periphery of the hole defines the point of crack initiation. Crack propagation modes are determined form stress and potential energy states in the vicinity of the initiation point. These mechanisms define direction and type of fracture mode. Fiber fracture releases far more energy than is required to generate an unstable crack. Quantitative definition of long term effects, such as crazing must be considered to successfully predict long term behavior of composite materials.
