Forming Analysis of Bulge Formed Joints Based on Adaptive Finite Element Method

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 ...

NURBS-Based Adaptive Finite Element Analysis

An Adaptive Finite Element Method

We develop an adaptive nite element algorithm for reactive ow simulations. The underlying equations are the Navier-Stokes equations for low-Mach-number ows and an additional system of convection-diiusion-reaction equations for the chemical species. Especially in combustion problems the reaction terms are very stii and nonlinear. This set of equations represents a complicated system of PDEs whic...

Determination of Buckling Limit of Strain in Cold Roll Forming through Finite Element Analysis

In this study, Buckling Limit of Strain (B.L.S.) is introduced as one of the most important limiting factors in cold roll forming process. B.L.S. is calculated by the finite element procedure. Then for two particular processes with existing analysis and experimental results, B.L.S. has been determined and evaluated. LUSAS 12.3 is used for finite element analysis. The results show that when buck...

A Super - Element Based on Finite Element Method for Latticed Columns Computational Aspect and Numerical Results

This paper presents a new super-element with twelve degrees of freedom for latticed columns. This elements is developed such that it behaves, with an acceptable approximation, in the same manner as a reference model does. The reference model is constructed by using many Solid elements. The cross section area, moments of inertia, shear coefficient and torsoinal rigidity of the developed new elem...
