摘要
Up to now the analysis on aisnotropic effects of quasi-isotropic composites to material structures has not been found in literatures. In the present paper the strength model for triaxial woven materials proposed in Part (I)[1]is applied to study the problems of an infintiely large plate of triaxial woven material containing either an either an elliptic hole or a crack. TO the elliptic hole problem the remote coritical loading as a function of the geometric parameters of woven materials is analysed and to the crack problem, the cracking orientation is examined. Finally the elasticity and strength models for a triaxial woven material proposed in Part (I)are verfied in terms of micromechanical analysis.
