Topology Optimization for Elasticity Problem of Isotropic and Orthotropic Materials Based on the Complex Variable Element-Free Galerkin Method

Yichen Yang,
Heng Cheng

Abstract: By using the improved complex variable moving least squares (ICVMLS) approximation to construct the shape function, thus the improved complex variable element-free Galerkin (ICVEFG) method is established for analyzing two types of topology optimization problems including isotropic and orthotropic materials in this study. Solid isotropic microstructure with penalization (SIMP) is utilized with relative density of nodes selected as the design variable, volume fraction set as the constraint and structural flexibi… Show more
