摘要: The local and overall responses of nonlinear composites are classically investigated by the Finite Element Method. We propose an alternate method based on Fourier series which avoids meshing makes direct use microstructure images. It is exact expression Green function a linear elastic homogeneous comparison material. First, case nonhomogeneous constituents considered iterative procedure proposed to solve Lippman-Schwinger equation naturally arises in problem. Then, extended non-linear step-by-step integration time. accuracy assessed varying spatial resolution microstructures. flexibility allows it serve for large variety
