Numerical Simulation of the Severe Cold Bending of Thick Steel Plates

This paper presents results of a finite element study of the severe cold bending of thick, high-strength steel plates using an explicit, two-dimensional, finite element code. A parametric study was performed to study the effect of contact surface conditions and the plate’s material model on the behavior of the plate during cold bending. The results of these numerical studies were compared with experimental data measured by Weng in 1984 and analytical equations proposed by Dat in 1980. It was found that the model with isotropic hardening and no friction showed the best agreement with the experimental and analytical results.
