Abstract

A formulation based on integral equations is proposed in order to analyse the edge-stress problem in composite laminates subjected to uniaxial extension. The integral equations are obtained by employing a direct approach founded on the reciprocity theorem. Once the fundamental solutions are known, the proposed formulation allows a straightforward solution of the problem by the boundary element method. The enforcement of displacement and traction continuity along the interfaces leads to a set of linear algebraic equations providing the problem solution. Some numerical applications are presented and good agreement between the results obtained with the proposed method and the existing ones is shown. The stress singularity arising at the laminate free edges is investigated determining its power and str
