Coupled Eulerian-Lagrangian (CEL) Modeling of Material Flow in Dissimilar Friction Stir Welding of Aluminum Alloys

In this work, the finite element simulation of dissimilar friction stir welding process is investigated. The welded materials are AA 6061-T6 and AA 7075-T6 aluminum alloys. For this purpose, a 3D coupled thermo-mechanical finite element model is developed according to the Coupled Eulerian-Lagrangian (CEL) method. The CEL method has the advantages of both Lagrangian and Eulerian approaches, whic...

Dynamic Analysis of Geotechnical Problems by Arbitrary Lagrangian-Eulerian Method

In this paper, an Arbitrary Lagrangian-Eulerian (ALE) method is addressed to solve dynamic problems involving large deformation. This ALE method is based upon the operator split technique in which the material displacements and mesh displacements are uncoupled. Special issues such as time-stepping, mesh refinement, dynamic equilibrium checks and remapping of state variables are briefly explaine...

Adaptive reconnection-based arbitrary Lagrangian Eulerian method: A-ReALE

W present a new adaptive reconnection-based arbitrary Lagrangian Eulerian: A-ReALE method. The main elements in a A-ReALE method are: An explicit Lagrangian phase on arbitrary polygonal mesh in which the solution and positions of grid nodes are updated; a rezoning phase in which a new grid is defined number of mesh cells, their location and connectivity (it is based on using Voronoi tessellatio...

ReALE: A reconnection-based arbitrary-Lagrangian-Eulerian method

We present a new reconnection-based Arbitrary Lagrangian Eulerian (ALE) method. The main elements in a standard ALE simulation are an explicit Lagrangian phase in which the solution and grid are updated, a rezoning phase in which a new grid is defined, and a remapping phase in which the Lagrangian solution is transferred (conservatively interpolated) onto the new grid. In standard ALE methods t...
