The traditional Lagrangian and Eulerian formulations in finite elements posses some inherent difficulties when used in simulation of metal-forming processes or general finite strain problems. A more general method of formulation, the Arbitrary Lagrangian-Eulerian (ALE), is developed to overcome such
An improved looping method for quadrilateral finite element generation, effective especially for automatic metal forming simulation, was presented in this paper. A new splitting criterion to improve the conventional looping method, an artificial boundary scheme to reduce mesh transition regions and
The paper presents an automatic finite element remeshing system for quadrilateral elements consisting of modules for mesh generation, densification, smoothing and interpolation of field variables. The mesh generator takes into account the contour of the old mesh, eventual interference with dies and
An automatic remeshing scheme has been developed to enable finite element simulation of even complicated forming processes. It has been demonstrated that for many practical applications the incorporation of this technique in the existing computer codes is indispensable not only for more accurate sol
This paper presents a new approach for obtaining the distribution of temperature in the dies during thermo-mechanical numerical analysis of metal forming problems. The proposed approach is based on a solution resulting from the combination of the finite element method with the boundary element metho
