A Novative Optimal Shape Design Based on an Isogeometric Approach: Application to Optimization of Surface Shapes With Discontinuous Curvature

Abstract : 1. Abstract When designing complex structures, optimization can play a major role. The most common procedure uses finite element analysis conducted on a mesh of the shape. Since the mesh is an approximation of the structure geometry, the quality of the simulations and consequently the optimization results are often downgraded. In this paper, we propose a computation method using the exact shape geometry for multi-shells structures. This method is based on isogeometric approach and allows to get better computation and optimization results.
