摘要
含圆孔纤维增强层合板的孔边层间应力研究属三维各向异性弹性力学范畴,是一个较复杂的问题。本文利用块体八结点各向异性等参元,求解了在两种平面载荷作用下,含不同圆孔孔径的多层纤维增强层合板孔边层间应力的分布。
A study of interlaminar stress at a hole in a composite laminarplate is a complicated subject. Its solution belongs to the three dimensionalanisotropic elasticity. This paper presents results from a numerical study of in-terlaminar stress distribution at a hole in a fiber laminate under axial tensionand compression loading.
