5. 내 용 : A failure theory for composite materials is presented that addresses the general condition in structural applications.  The general condition in- cludes all possible boundary conditions, loading conditions, geometric configurations and lamina stacking sequences.  The theory is supported with a minimal set of effective critical lamina properties extracted from


a small set of test coupons and the finite element method.  The validity


of the theory is demonstrated through the simulation of failure in


complex laminates such as angle-ply laminates (matrix load path) and


open-hole tension (fiber load path).
