An equivalence between the enhanced assumed strain (EAS) method based on the Hu-Washizu principle, recently proposed by Simo and Rifai, and assumed stress hybrid (hybrid) method based on the Hellinger-Reissner principle is investigated. It is proved that not only the displacements but also the stres

A classification method is presented to classify stress modes in assumed stress fields of hybrid finite element based on the eigenvalue examination and the concept of natural deformation modes. It is assumed that there only exist m ( "n!r) natural deformation modes in a hybrid finite element which h
We present strong and weak forms of boundary-value problems for a solid with a cohesive-frictional crack. Two commonly used techniques for enhancing the finite element (FE) interpolation are considered: the assumed enhanced strain (AES) and the extended FE methods. We compare and contrast the FE app
