Some Remarks on Generalized Finite Element Methods (GFEM) in Solid Mechanics
نویسندگان
چکیده
After a short introduction to Generalized Finite Element Methods (GFEM) for two-dimensional triangular elements, a technique is presented to impose Dirichlet-type boundary conditions to global higher order GFEM ansatz spaces. The convergence rates of h-, p-, hp-and enriched p-versions of the GFEM are discussed with respect to singularities. The method is applied to a two dimensional Poisson model problem and the global errors measured in energy norm are compared.

Generalized ®nite element methods for three-dimensional structural mechanics problems
The present paper summarizes the generalized ®nite element method formulation and demonstrates some of its advantages over traditional ®nite element methods to solve complex, three-dimensional (3D) structural mechanics problems. The structure of the stiness matrix in the GFEM is compared to the corresponding FEM matrix. The performance of the GFEM and FEM in the solution of a 3D elasticity pro...
متن کاملAnalysis of three-dimensional fracture mechanics problems: A non-intrusive approach using a generalized finite element method
This paper shows that the generalized finite element method with global–local enrichment functions (GFEM) can be implemented non-intrusively in existing closed-source FEM software as an add-on module. The GFEM is based on the solution of interdependent global (structural) and local (crack) scale problems. In the approach presented here, an initial global scale problem is solved by a commercial ...
متن کاملComparison of different numerical methods for calculating stress intensity factors in analysis of fractured structures
In this research, an efficient Galerkin Finite Volume Method (GFVM) along with the h–refinement adaptive process and post–processing error estimation analysis is presented for fracture analysis. The adaptive strategy is used to produce more accurate solution with the least computational cost. To investigate the accuracy and efficiency of the developed model, the GFVM is compared with two versio...
متن کاملParticle–partition of Unity Methods in Elasticity
The particle–partition of unity method (PUM) [1, 2, 3, 4, 5, 8] is a meshfree Galerkin method for the numerical treatment of partial differential equations (PDE). In essence, it is a generalized finite element method (GFEM) which employs piecewise rational shape functions rather than piecewise polynomial functions. The PUM shape functions, however, make up a basis of the discrete function space...
متن کاملGeneralized Finite Element Methods: Main Ideas, Results, and Perspective
This paper is an overview of the main ideas of the Generalized Finite Element Method (GFEM). We present the basic results, experiences with, and potentials of this method. The GFEM is a generalization of the classical Finite Element Method — in its h, p, and h-p versions — as well as of the various forms of meshless methods used in engineering.
