一种基于Ishai应力准则的双方向结构拓扑优化方法
A Bi-directional Optimization Method of Structural Topology Based on Ishai Stress Criteria
【摘要】 在传统的ESO方法基础上,考虑到Ishai应力准则对工程结构材料有广泛的适用性,研究了基于Ishai应力准则的双方向渐进拓扑优化方法。该方法是对传统方法和目前的双方向法的改进。算例表明,该方法对桥梁等混凝土结构有广泛的工程应用价值。
【Abstract】 Based on the traditional evolutionary structural optimization(ESO) and considering the wide (adaptability) of Ishai stress criteria for engineering structure,the authors present a bi-directional structural optimization method based on the Ishai stress optimization criterion. Finally, some numerical examples are given and they show that this method can be applied widely in the engineering designs for bridge structures, concrete structures and etc.
