Shape Optimization of Dynamic Structural Member in Isogeometric Analysis

Abstract

We establish computational schemes for shape optimization of structural member in Isogeometric analysis (IGA). The target structure is a dynamic three-point bending analysis of a hat member. In conventional finite element analysis, drastic shape change and arriving at the true optimal shape is extensively difficult. In this study, by searching optimal shape utilizing IGA data characteristics, compatibility with digital data and convergence to the optimum solution is investigated.
