Coupling of Natural Boundary Element Method and Finite Element Method for Three-dimensional Nonlinear Interface Problem
Coupling of Natural Boundary Element Method and Finite Element Method for Three-dimensional Nonlinear Interface Problem Hong-ying Huang2,1 and De-hao Yu 2 Summary In this paper, we apply the coupling of natural boundary element method and finite element method to solve a three-dimensional nonlinear interface problem. Two equations are coupled by interface conditions on the interface boundary. A...
متن کاملA T -ψ Finite Element Method for a Nonlinear Degenerate Eddy Current Model with Ferromagnetic Materials
This paper is devoted to the study of a fully discrete T -ψ finite element method based on H-decomposition to solve a nonlinear degenerate transient eddy current problem with ferromagnetic materials. Here, the ferromagnetic properties are linked by a power material law. We first design a nonlinear time-discrete scheme for approximation in suitable function spaces. We show the well-posedness of ...
متن کاملA New Stress Based Approach for Nonlinear Finite Element Analysis
This article demonstrates a new approach for nonlinear finite element analysis. The methodology is very suitable and gives very accurate results in linear as well as in nonlinear range of the material behavior. Proposed methodology can be regarded as stress based finite element analysis as it is required to define the stress distribution within the structural body with structural idealization a...
متن کاملA Computer Program for 2d/rs Eddy Current Problem Based on Boundary Element Method
A computer program, OERSTED, for simulating and analyzing two-dimensional or rotational symmetric eddy current problem with the steady-state sinusoidal time-varying source excitation has been developed at the Integrated Engineering Software (IES). Like other widely used CAE tools developed at IES, OERSTED is a software package based on the most advanced Boundary Element Method (BEM) technique. ...
