Conception optimale des pieces mecaniques modelisees par des coques minces
Keywords:
finite element method, thin shell, sensitivity analysis,, thickness optimization, mass minimization, Von Mises stress minimizationAbstract
This paper is concerned with a numerical method to solve some thin shell optimization problems. The junctions to minimize or to limit are the mass and the Von Mises stress. Sensitivity analysis is developed in the discrete case. Numerical results are presented for an aeronautic piece (gear case) of complex shape.
