Fixed-point fluid–structure interaction solvers with dynamic relaxation
A fixed-point fluid–structure interaction (FSI) solver with dynamic relaxation is revisited. New developments and insights gained in recent years motivated us to present an FSI solver with simplicityExpand

An eXtended Finite Element Method/Lagrange multiplier based approach for fluid-structure interaction
Abstract This paper presents a new fixed grid fluid–structure interaction scheme that can be applied to the interaction of most general structures with incompressible flow. It is based on an eXtendedExpand

A Comparison of Diameter, Wall Stress, and Rupture Potential Index for Abdominal Aortic Aneurysm Rupture Risk Prediction
An abdominal aortic aneurysm (AAA) is a balloon-like dilation of the aorta, which is potentially fatal in case of rupture. Computational finite element (FE) analysis is a promising approach to a moreExpand

Isogeometric structural shape optimization
An old dilemma in structural shape optimization is the needed tight link between design model or geometric description and analysis model. The intention of this paper is to show that isogeometricExpand

An embedded Dirichlet formulation for 3D continua
This paper presents a new approach for imposing Dirichlet conditions weakly on non-fitting finite element meshes. Such conditions, also called embedded Dirichlet conditions, are typically, but notExpand
