摘要
本文给出了单向拉伸与面内剪切载荷下夏合材料对称层合板中心区域的应力和应变沿板厚的数值计算分布规律．计算结果表明，在斜交对称铺层的层合板中心区域层间界面附近存在着层间边界层效应．层间界面处纤维走向的突变导致局部的三维应力状态和很强的应力集中．
This paper presents the stress and strain distribution obtained numerically inthe thickness direction in the central region of symmetric composite laminatesunder uniaxial extension in-plane pure shear loading,It is shown that in the sym-metric angle-ply laminates,near the interlaminar surface,there is an interlaminar boundary-layer effect.The abrupt change of the fiber orientation at the interla-minar surface causes a high concentration of stresses and a local three dimensional stress state.
