## Abstract

Simulating fluid-structure interactions is challenging due to the tight coupling between the solid and fluid substructures in a moving domain. Explicit and implicit decoupling methods often either fail or require relaxation when densities of the two materials are close. In this talk both monolithic and decoupling approaches are considered for analytical and numerical studies of fluid-structure interaction problems where a fluid is governed by a Newtonian or non-Newtonian model. An optimization based method which allows the problems to be stably decoupled is discussed and numerical results are presented.
