This paper reviews the most recent models for description of the anisotropic plastic behavior
and formability of sheet metals. After a brief review of classic isotropic yield functions, recent …

This paper is concerned with modeling of fracture-based forming limit criteria for anisotropic
materials in sheet metal forming to predict the sudden fracture in complicated forming …

The goal of this contribution is to formally present an incremental damage model conceived
to predict failure of ductile materials in forming and crash applications. Denoted henceforth …

In sheet metal forming processes, formability is a critical material property that needs to be
estimated before the production of forming parts. Some popular tools used in the literature to …

Many practitioners of the metal forming community remain faithful to the idea that strain
metrics are useful for formability assessment, while many others who are aware of the …

This paper aims to estimate and analyze both the necking and fracture based path-
independent forming limit criteria during two-stage forming of anisotropic sheet materials. In …

This work describes a new procedure to remove the differences in measured forming limits
obtained from Marciniak and Nakazima tests, which are the two most frequently used testing …

In the common industrial thin sheet metal forming process at room temperature, in which in-
homogenous deformation under the plane stress condition is typically the case, sheets are …

The formability of the material determines the amount of available deformation before failure
and thus is important for the production of various structural components in industries. The …

Abstract The Forming Limit Diagram (FLD) is a conventional failure diagram to estimate
necking limits of sheet metal for proportional loading conditions. Previous studies reveal that …
