Title of the contribution: Tangential-Displacement and Normal-Normal-Stress Continuous Mixed Finite Elements for Elasticity
Abstract:
In this talk we introduce new finite elements to approximate the Hellinger Reissner formulation of elastictiy. The elements are the vector valued tangential continuous Nedelec elements for the displacements, and symmetric, tensor valued, normal-normal continous elements for the stresses. These elements do neither suffer from volume locking as the Poisson ratio approaches 1/2, nor
suffer from shear locking when anisotropic elements are used for thin structures.
