Elasto-plastic finite element simulation of asymmetrical plate rolling using an ALE approach

Asymmetric sheet rolling is simulated by using an elastic–plastic arbitrary Lagrangian–Eulerian (ALE) finite element method. The ALE finite element approach easily predicts the curvature development due to inequality in work roll/plate surface finish (interface friction) and speed mismatch. An isotropic work hardening material is assumed. Reasonable agreements were found between the numerical method and the experimental results.
