Abstract

Pseudo-ductile thin-ply composites loaded in tension exhibit a non-linear stress-strain response with a plateau, analogous to yielding in a metal. This provides an alternative means for load redistribution at stress concentrations, giving reduced notch-sensitivity. The notched tensile response of both thin-ply hybrid and angle-ply laminates is presented, and the failure mechanisms described and compared with those of conventional composites to explain the reduced notch sensitivity.
