Boundary-layer effects in composite laminates: Free-edge stress singularities, part 6 [PDF]

A rigorous mathematical model was obtained for the boundary-layer free-edge stress singularity in angleplied and crossplied fiber composite laminates. The solution was obtained using a method consisting of complex-variable stress function potentials and ...
