Abstract Based on the meso-mechanical model established for T6-treated SiCP/6061Al alloy composites, the monotonic tensile and uniaxial cyclic deformation behaviors of the composites were simulated numerically by using elastic-plastic finite element code ABAQUS; and then the simulated results were compared with the corresponding experiments in order to discuss the reasonability of the finite element simulation. It is shown that: since a newly developed cyclic constitutive model describing the ratcheting behavior reasonably is employed for T6-6061Al alloy matrix, the finite element model established in this work simulate the uniaxial cyclic deformation of the composites well, especially for the ratcheting behavior. It is also shown that the cyclic deformation of the composites is heterogeneous and complicated in meso-scale.
