2. 1. Finite Element Procedures for Fluid-structure Interaction

   Author : Joakim Hermansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nitsche s method; stabilized Crouzeix-Raviart; Winslow s method; Raviart-Thomas; space-time FE; stretched elements; FSI; FEM; weak coupling; mesh smoothing; acoustic FSI; ALE;

   Abstract : This thesis concerns finite element (FE) methods for solving fluid-structure interaction (FSI) problems. Two types of fluid-structure interaction are considered. A finite element method for solving the interaction between a flowing incompressible fluid and a linear elastic structure is proposed. The flow is assumed to be laminar. READ MORE
