Application of a Discontinuous Petrov-Galerkin (DPG) method for simulation of compressible viscous flows in three dimensions is presented. The approach enables construction of stable schemes for problems with a small perturbation parameter. The main

A mixed finite element formulation for compressible finite hyperelasticity, possibly with strongly deformation dependent stiffening fibre reinforcement, is developed and verified. Reinforcement by two, mechanically equivalent, in general oblique, fib

We propose a novel finite element based formulation for the solution of the static mechanical mixed boundary value problem of a finite elastic solid reinforced by two distinct, stiff fibre families. The fibre tensions, are assumed decoupled and uniax

A higher order mixed finite element method is presented for compressible transversely isotropic finite hyperelasticity. The independent variables of the three-field formulation are; displacement, fibre tension and fibre stretch. The formulation admit

In this work we present a generalization of the mortar segment-to-segment method for finite deformations contact to an h-adaptive version with possible p extension, i.e. using higher order approximation. We recall the main ideas of the mortar algorit

The Discontinuous Petrov-Galerkin (DPG) method allows one to construct stable finite element schemes for some classes of singularily perturbed problems like, for instance, convection-dominated diffusion. The central ingredient of the method is a spec
