摘要：
In this paper, the influence of the pattern of finite elements mesh, such as finite element density and shape, on optimum distribution of members is studied. Two classical Michell trusses are employed to demonstrate the stability of topology optimization results obtained based on continuous distribution of members. In the two examples, design region are divided by different element meshes. It is showed that this method used in this paper is less sensitive to the density and pattern of finite elements mesh.
