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...
