چکیده
An interface/boundary-unfitted eXtended hybridizable discontinuous Galerkin (X-HDG) method of arbitrary order is proposed for linear elasticity interface problems on unfitted meshes with respect to the and domain boundary. The uses piecewise polynomials degrees \(k\ (\ge 1)\) \(k-1\) respectively displacement stress approximations in interior elements inside subdomains separated by interface, degree k numerical traces inter-element boundaries interface/boundary domain. Optimal error estimates \(L^2\)-norm are derived. Finally, experiments confirm theoretical results show that also applies case crack-tip

eXtended Hybridizable Discontinous Galerkin (X-HDG) for Void Problems
A strategy for the Hybridizable Discontinous Galerkin (HDG) solution of problems with voids, inclusions or free surfaces is proposed. It is based on an eXtended Finite Element philosophy with a level-set description of interfaces. Thus, the computational mesh is not required to fit the interface (i.e. the boundary), simplifying and reducing the cost of mesh generation and, in particular, avoidi...
متن کاملAn Algebraic Multigrid Method for Linear Elasticity
We present an algebraic multigrid (AMG) method for the efficient solution of linear (block-)systems stemming from a discretization of a system of partial differential equations (PDEs). It generalizes the classical AMG approach for scalar problems to systems of PDEs in a natural blockwise fashion. We apply this approach to linear elasticity and show that the block-interpolation, described in thi...
متن کاملAn Unfitted Discontinuous Galerkin Method Applied to Elliptic Interface Problems
In this article an unfitted Discontinuous Galerkin Method is proposed to discretize elliptic interface problems. The method is based on the Symmetric Interior Penalty Discontinuous Galerkin Method and can also be interpreted as a generalization of the method given in [A. Hansbo, P. Hansbo, An unfitted finite element method based on Nitsche’s method for elliptic interface problems, Comp. Meth. A...
متن کاملHybrid Stress Finite Volume Method for Linear Elasticity Problems
Abstract. A hybrid stress finite volume method is proposed for linear elasticity equations. In this new method, a finite volume formulation is used for the equilibrium equation, and a hybrid stress quadrilateral finite element discretization, with continuous piecewise isoparametric bilinear displacement interpolation and two types of stress approximation modes, is used for the constitutive equa...
متن کاملA ctitious domain method for linear elasticity problems
A ctitious domain method based on boundary Lagrange multipliers is proposed for linear elasticity problems in two dimensional domains. The solution of arising saddle-point problem is obtained iteratively using MINRES method with a positive deenite block diagonal preconditioner which is based on a fast direct solver for diiusion problems. Numerical experiments demonstrate the behavior of conside...
