Method of Forging Process Simulation Using Particle Flow Model

Abstract

The particle flow model is proposed as an improved finite element method for the analysis of metal forging processes. The forged material in the present modeling is analyzed in conjunction with non-material domain, and the process is expressed not by the finite element deformation but by "the movable particle" which discriminates the material domain. The finite element only has a role to give the node velocities which prescribe to the particle where to move. This "fixed" mesh algorithm will free program developers from complicated folding treatment and will free users from irksome task of remeshing as well. This paper describes the outline of the concept and some application examples of two dimensional axisymmetric problem.
