Finite element and boundary element contact stress analysis with remeshing technique

Adaptive Remeshing Method via Inversion of Element Anisotropy in Large Deformation Finite Element Analysis

The large deformation finite element analysis such as metal forming analysis usually involves processes to deform, stamp, or punch a part drastically, which causes great changes in shape of the part during the simulation. As the part is reshaped, the mesh elements are deformed, and element shape quality is decaying as analysis continues. To resolve this problem, it is common to adaptively remes...

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...

Finite element analysis of nonsmooth contact

This work develops robust contact algorithms capable of dealing with complex contact situations involving several bodies with corners. Amongst the mathematical tools we bring to bear on the problem is nonsmooth analysis, following [14]. We speci cally address contact geometries for which both the use of normals and gap functions have difculties and therefore precludes the application of most co...

Evaluation of Fracture Parameters by Coupling the Edge-Based Smoothed Finite Element Method and the Scaled Boundary Finite Element Method

This paper presents a technique to evaluate the fracture parameters by combining the edge based smoothed finite element method (ESFEM) and the scaled boundary finite element method (SBFEM). A semi-analytical solution is sought in the region close to the vicinity of the crack tip using the SBFEM, whilst, the ESFEM is used for the rest of the domain. As both methods satisfy the partition of unity...
