Abstract:
The Forming Limit Curve (FLC) is a conventional failure criterion to estimate sheet metal formability for proportional loading conditions in Finite Element Analysis. Previous studies found that a standard FLC is not suitable for predicting the influence of nonlinear strain paths. This paper introduces a new method for the description of failure behavior in two-step forming operations by using a metamodeling technique. The main objectives of this approach are the cost effectiveness of the require...     »
