In order to simulate the deep-draw forming process for composite materials with complex microstructure, a novel computational method that takes the microscopic large deformation into consideration is proposed. The microstructure of composite materials affects the deep-draw forming process. The proposed method decouples this complicated problem into macro- and microscopic problems by means of homogenized nonlinear material properties, which contributes much to the computational cost effectiveness. First, using the large deformation analysis and homogenization, the homogenized nonlinear properties considering the microstructural geometrical nonlinearity are obtained by microscopic analyses. Secondly, the deep-draw forming analysis is carried out macroscopically with precalculated material database. This material database consists of 21 independent parameters given by microscopic analyses, and is referred with respect to three macroscopic strain parameters. An example of deep-draw forming simulation for a formed core is shown.
