AbstractA finite element (FE) model of particle reinforced metal matrix composite (PRMMC) was developed by considering load transfer, grain refinement, thermal residual stress/strain, plastic strain gradient and damage of the matrix together. This new model provides precise prediction of the tensile stress-strain curves of PRMMC, even when the size of particles varies. Using the new model, the effect of each strengthening mechanism was assessed quantitatively. According to the results, grain refinement is the main reason causing size effect, while strain gradient only causes higher work hardening rate for PRMMC with smaller particles. Load transfer plays a dominant role among other strengthening mechanisms. Residual stress/strain shows steady but small effect in strengthening PRMMC.
