The aim of this work is to find optimum shapes of holes in shear panels made of carbon/epoxy composite materials. The study is restricted to non-buckling shear panels, and a simplified fracture criterion is applied. Starting with a baseline square shear panel with a circular hole, the optimization results in a larger non-circular hole that gives the same maximum stress level in the laminate. Optimum shaped holes are determined for four different laminate configurations, the differences between the shapes being small.
