摘要：
To prevent the numerical instabilities about checkerboards, mesh-dependency and gray-scale elements in structural topology optimization with strain energy constraints, an improved ICM method based on the bi-directional filter function is presented. The sequential quadratic approximate algorithm is applied to solve the optimal model for continuum structure established in this paper. A classical numerical example is discussed which shows that the present method is effective and efficient.
