Abstract

Abstract

This paper presents the stress and strain distribution obtained numerically in the thickness direction in the central region of symmetric composite laminatesunder uniaxial exlension and in-plane pure shear loading. It is shown that in the symmetric angleply 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.
