Weakly symmetric stress reconstruction and a posteriori error estimation for linear elasticity |

| 초록본문(Abstract) | In this talk, a stress reconstruction in the H(div)-conforming Raviart-Thomas space based on the Taylor-Hood displacement-pressure approximation procedure for linear elasticity is proposed. The construction is weakly symmetric and the computation is performed locally on a set of vertex patches. Due to the weak symmetry constraint, the local problems need to satisfy consistency conditions associated with all rigid body modes. The resulting error estimator constitutes a guaranteed upper bound for the error and is shown to be local efficient. |
