Adjoint shape optimization for fluid–structure interaction of ducted flows
Based on the coupled problem of time-dependent fluid–structure interaction, equations for an appropriate adjoint problem are derived by the consequent use of the formal Lagrange calculus. Solutions of both pri...

Finite cell method compared to h-version finite element method for elasto-plastic problems
The finite cell method (FCM) combines the high-order finite element method (FEM) with the fictitious domain approach for the purpose of simple meshing. In the present study, the FCM is used to the Prandtl-Reus...

A comparison of the h-, p-, hp-, and rp-version of the FEM for the solution of the 2D Hertzian contact problem
Even after more than three decades of intensive research in the field of contact mechanics, there is still a great need for improving the numerical methods. Recent investigations on the 2D Hertzian contact pro...

An Explicit Model for Three-Dimensional Fluid-Structure Interaction using LBM and p-FEM
An explicit coupling model for the simulation of surface coupled fluid-structure interactions with large structural deflections is introduced. Specifically, the fluid modeled via the Lattice Boltzmann Method (...

Open AccessNumerical investigations of foam-like materials by nested high-order finite element methods
In this paper we present a multiscale framework suited for geometrically nonlinear computations of foam-like materials applying high-order finite elements (p-FEM). This framework is based on a nested finite eleme...

A Numerical Investigation of High-Order Finite Elements for Problems of Elastoplasticity
A high order finite element approach is applied to elastoplastic problems in two as well as in three dimensions. The element formulations are based on quadrilaterals and hexahedrals, taking advantage of the bl...
