Weakly symmetric stress equilibration for hyperelastic materialmodels
Fleurianne Bertrand, Marcel Moldenhauer, Gerhard Starke
A stress equilibration procedure for hyperelastic material models is proposed andanalyzed in this paper. Based on the displacement-pressure approximation computed with a stable fin…

Weakly symmetric stress equilibration and a posteriori error estimation for linear elasticity
Fleurianne Bertrand, Bernhard Kober, Marcel Moldenhauer +1
A stress equilibration procedure for linear elasticity is proposed and analyzed in this paper with emphasis on the behavior for (nearly) incompressible materials. Based on the disp…

A posteriori error estimation for planar linear elasticity by stress reconstruction
Fleurianne Bertrand, Marcel Moldenhauer, Gerhard Starke
The nonconforming triangular piecewise quadratic finite element space by Fortin and Soulie can be used for the displacement approximation and its combination with discontinuous pie…
