Abstract
A comparison is made between Arbitrary Lagrangian-Eulerian (ALE) finit e element formulations for simulation of forming processes based on an artificial dissipation scheme and a limited flux scheme. The first AL E algorithm is based on an averaging procedure used in post-processing of finite element calculations. The second ALE algorithm stems from a finite difference method for compressible fluid dynamics. Both approa ches have complementary characteristics with respect to accuracy and i mplementation.
