## Abstract The extended finite element method (XFEM) is applied to the simulation of thermally stressed, cracked solids. Both thermal and mechanical fields are enriched in the XFEM way in order to represent discontinuous temperature, heat flux, displacement, and traction across the crack surface,

Static fracture analyses in two-dimensional linear magnetoelectroelastic (MEE) solids is studied by means of the extended finite element method (X-FEM). In the X-FEM, crack modeling is facilitated by adding a discontinuous function and the crack-tip asymptotic functions to the standard finite elemen
An analysis of some nonconforming approximations of the Stokes problem is presented. The approximations are based on a strain-pressure variational formulation. In particular, a convergence and stability result for a method recently proposed by Bathe and Pantuso is provided.
We derive stability properties and error estimates for the finite element method when used to approximate heat flow in a fluid enclosed by a solid medium. The coupled Navier Stokes system involves the Boussinesq equations in the fluid-filled cavity linked through an interface with heat conduction in
