Abstract: | Up to now, the analysis on anisotropic 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)

is applied to study the problems of an infinitely large plate of triaxial woven material containing either an elliptic hole or a crack. To the elliptic hole problem the remote critical 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 verified in terms of micro-mechanical analysis.Project supported by the National Natural Science Foundation of China and the State Education Commission Foundation of China |
