中文摘要	The bearing capacity of ductile composites was analyzed for variable loadings by using homogenization theory from micromechanics for the macroscopic plastic analysis. The composite microstructure is represented using a representative volume element. The limit load of a microstructure volume element is calculated by introducing homogenization theory into the static shakedown analysis. The static shakedown approach is solved using the finite element method as a constrained nonlinear programming problem which is then solved using the sequential quadratic programming method. This method is more efficient, especially for studying the macroscopic plasticity properties of periodical ductile composites.
