In this paper, topology optimization of structures is achieved through integrating the element free Galerkin (EFG) method and the solid isotropic method with penalization (SIMP). The strain energy is minimized as objective function. In the proposed method the density is assigned to the Gauss points to obtain an acceptable resolution. Irregular distribution of nodes has also been used in this study. Several benchmark examples were applied to demonstrate the ability of the proposed algorithm and the obtained results compared to the other previous works.

不规则节点分布的无单元Galerkin方法优化连续体结构的拓扑

本文通过结合无元素伽勒金（EFG）方法和带罚分的固体各向同性方法（SIMP）来实现结构的拓扑优化。作为目标函数，应变能被最小化。在提出的方法中，将密度分配给高斯点以获得可接受的分辨率。节点的不规则分布也已用于本研究中。与其他以前的工作相比，应用了几个基准示例来证明所提出算法的能力以及所获得的结果。
