Abstract
This paper presents the stress and strain distribution obtained numerically in the thickness direction in the central region of symmetric composite laminates under uniaxial extension and in-plane pure shear loading. It is shown that in the symmetric angle-ply laminates, near the interlaminar surface, there is an interlaminar boundary-layer effect. The abrupt change of the fiber orientation at the interlaminar surface causes a high concentration of stresses and a local three dimensional stress state.
