• In order to understand the compressive behaviors of particle-reinforced metal-matrix composite (MMCs) material for its potential usage on light armor, large compressive plastic deformation of MMC composite is investigated through numerical modeling at high strain rates. Based on the work of Li and Remash, the numerical modeling is performed using axisymmetric unit cell model, with the particles treated as elastic ellipsoids or cylinders embedded within a visco-plastic matrix. Five particle volume fractions from 10% to 50% and three aluminum matrix materials LY12CZ, LC4 and 7075 are analyzed. The contribution of this work is to add a term to the original analytical model. Thus it can take account the effect of strain hardening of the matrix material. The modified analytical model introduced here is able to better describe the features of the computational predictions at certain extent.
