Abstract
The yield criterion is an essential component of the mechanical models used for the simulation of sheet metal forming processes. Its capability to describe the anisotropic response of cold-rolled products has a significant influence on the quality of the numerical results. This paper gives a short description of the BBC 2005 yield criterion which is implemented in the finite-element code AutoForm 4.1.1. With the aim of proving the performances of the BBC 2005 model, the results of a standard test (Numisheet 2005 Benchmark#1 – numerical simulation of the deep-drawing and springback of a decklid inner panel) are also presented.
