To the minimizing structural compliance problems which widely occur in engineerings for a maximum structural stiffness design, an optimization model with reciprocal variables was established by the SIMP method. An optimality criterion is proposed by the K-T condition. Compliance filtering method is proposed to eliminate numerical problems such as checkerboard patterns and mesh dependency problems. With different scales of optimization problems, the solution efficiency is compared with the original criteria method and MMA method; and the optimal...
