摘要：

Within the framework of linear elasticity the free-edge effect of a symmetric cross-ply laminate is treated in a closed-form analytical way. To this end a higher-order plate theory approach is used. The essential characteristic of the present analysis is the introduction of a warp deformation mode for the near-edge displacements. For a laminate coupon under uniaxial tension the displacement field and the accompanying stresses are determined. In particular, this includes the straightforward calculation of the interlaminar stress components.
