A first order approach for worst-case shape optimization of the compliance for a mixture in the low contrast regime

摘要: The purpose of this article is to propose a deterministic method for optimizing structure considering its worst possible behaviour when small uncertainty exists over Lame parameters. idea take advantage the parameter derive an asymptotic expansion displacement and compliance with respect contrast in coefficients. We are then able compute case design as post-treatment computation field nominal domain evolution resulting from optimization performed here using level set method. computational cost our remains same order homogeneous material.
