Level Set Method for Shape and Topology Optimization of Contact Problems

Abstract: Abstract. This paper deals with simultaneous topology and shape optimization of elastic contact problems. The structural optimization problem for an elastic contact problem is formulated. Shape as well as topological derivatives formulae of the cost functional are provided using material derivative and asymptotic expansion methods, respectively. These derivatives are employed to formulate necessary optimality condition for simultaneous shape and topology optimization and to calculate a descent direction in num… Show more

“…In future studies, the method needs to be expanded onto problems with multiple phases, where one of them could be void. Finally, the method should be augmented by topological derivatives to mitigate the dependence of the optimization results on the initial design; see for example Sokolowski and Zochowski (2005) and Myśliński (2009).…”

“…Myślińsky pioneered level set methods for shape and topology optimization of unilateral contact problems where one of the bodies is rigid; see for example Myśliński (2009), Myśliński (2013, Myśliński (2014) and Myśliński (2015). The finite element method in combination with an Ersatz material approach is used to model contact problems with and without friction.…”

“…The material derivative method is employed in monograph [2] to calculate the sensitivity of solutions to contact problems as well as the derivatives of domain depending functionals with respect to variations of the boundary of the domain occupied by the body. Shape optimization of a dynamic contact problem with a given Coulomb friction and heat flow is considered in [3]. In this paper the material derivative method is employed to formulate a necessary optimality condition.…”
