摘要：
In this paper, a two-dimensional damage model and its numerical solution are presented by means of fast Fourier transforms for anisotropic composite. First, the constitutive relation with damage variable is given from strain energy density based on the two-dimensional constitutive relation of anisotropic composites. Second, the crack growth principle is given according to maximum K criterion. Finally, a numerical solution can be obtained using the fast Fourier transforms method. Numerical examples of carbon-fibre unidirectional reinforced resin matrix composite are introduced.
