| 摘 要： | 在传统渐进结构优化方法基础上，采用统一强度理论提出了一种对各种性能工程材料普遍适用的统一强度双向渐进结构拓扑优化方法。该方法既可以对各向同性材料进行拓扑优化，也可以对实际工程中普遍存在的各向异性材料进行拓扑优化。算例表明，该方法不但适用于土建工程等脆性材料结构拓扑优化设计，而且在各向异性材料加工和模具设计领域具有广泛用途。

| Abstract: | Based on the traditional evolutionary structural optimization method and considering wide applications of the unified strength theory for all kinds of engineering structures, this paper presents a bi-directional evolutionary structural topology optimization method based on the unified strength criterion. It can be used not only for isotropic materials, but also for many kinds of anisotropic materials. Finally, some numerical examples are given, and the results show that this method has wide use in topology optimization design for structures of fragile materials, the anisotropic material processing and die design fields. |
