Finite Element Analysis Based on Volume CAD

Concepts of Cad-integrated Finite Element Analysis

A CAD system contains only part of the information required for structural analysis, namely, geometrical data. In order to generate a finite element model, the CAD geometry needs to be simplified, e.g. by dimensional reduction. Furthermore, information on boundary conditions and loading needs to be supplied. These tasks cannot be performed solely on the basis of a geometrical model, but require...

Finite element analysis of 2-D representative volume element

An Adaptive Surface Finite Element Method Based on Volume Meshes

In this paper we define an adaptive version of a recently introduced finite element method for numerical treatment of elliptic partial differential equations defined on surfaces. The method makes use of a (standard) outer volume mesh to discretize an equation on a two-dimensional surface embedded in R3. Extension of the equation from the surface is avoided, but the number of degrees of freedom ...

A 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...
