Topological optimization design of multiphase materials under multiple operating conditions

Abstract In existing structural topology optimization methods, the main focus is on the topology optimization problem under single operating conditions. However, under various operating conditions, there is uncertainty and complexity among the operating conditions. This paper, based on the topology optimization technology of continuum structures in multiphase materials, conducts relevant research on the structural optimization problem of multiphase materials under multiple working conditions with volume constraints and minimum structural flexibility as the objective. The results show that under multiple operating conditions, the optimized structural topology is clear and has good 0/1 characteristics.
