Numerical model for the oil pressure distribution in the hydromechanical deep drawing process

This paper presents an attempt to simulate the hydromechanical deep drawing process using the finite element method (FEM). The basic idea is to compute the counter pressure and the fluid film pressure by solving a finite difference approximation of Reynold’s equation. The concept is implemented as a contact algorithm in Exhale2D, an explicit finite element code for two-dimensional analyses. The numerical results illustrate a rather good agreement with experimental data.
