The optimization of fiber distribution is analyzed in order to improve the strength performance of metal‐matrix composite material, which is submitted to two variable independent loads by coupling homogenization and shakedown theories. Numerical Direct Methods are applied to acquire the shakedown domain of three‐dimensional heterogeneous elastic‐perfectly plastic fiber‐reinforced composite for optimal design.
