Abstract: A material-based subdomain hybrid cellular automata algorithm for solving material optimization of thin-walled frame structures includes an outer loop and an inner loop. The outer loop is to define and update the target cost for the inner loop, and the inner loop is to adjust material using a PID control strategy according to the nominal flow stress of a current cell and the nominal flow stress of candidate materials, so that a current cost of the inner loop converges to the target cost. The material-based subdomain hybrid cellular automata algorithm can effectively solve a nonlinear dynamic response optimization problem in the discrete design space.
