Abstract : Failure surface of laminated composites can be constructed in special strain space such that the transformation of strain components becomes an orthogonal matrix. This construction provides a convenient means of studying strength of laminates consisting of arbitrary lamina orientations. This special construction of failure surface can be based on the maximum strain theory, the tensor polynomial theory or other failure criteria of the lamina. The effect of nonlinearity due to shear on the failure surface is also illustrated.
