Simulation of slab rolling process with rigid visco - Plastic finite element method

Journal Article


Abstract


  • The presented paper combined the Shifted Incomplete Cholesky decomposition of the stiffness matrix with Conjugate Gradient method for the solution of the equations of velocity increment. This technique, termed the shifted ICCG method, is then employed in the rigid visco-plastic finite element method to solve the slab-rolling problem. The number of iterations, shifted parameter ψ and the results of simulation for process parameters have been analyzed. The efficiency and stability of the shifted ICCG method in the analysis of slab rolling was verified.
