Formability of AA7021-T4 Sheet Alloy Under Changing Strain Path Conditions: Experiments and Crystal Plasticity Modeling

Crystals
The formability of AA7021-T4 sheets under changing strain paths was investigated via a novel crystal plasticity model and associated experimentation. The motivation was to advance simulation tools for process design of limited-ductility 7xxx alloys, with

Prediction of Forming Limit Diagram for Ti-6Al-4V Alloy Using Artificial Neural Network

, 2014
In sheet metal industries, the ability to predict and avoid failures, such as necking, fracture and wrinkling are of great importance. It is important to work within the safe strain region to avoid these failures.

Determination and Modeling of the Forming Limit Diagram for thin Ferritic Stainless Steel Sheet

, 2011
MasterThe forming limit diagram (FLD) of a 0.098mm-thick sheet of a ferritic stainless steel was determined using a modified Marciniak test. The Nakazima test was alsotried, but the test produced wrinkling on the sheet specimens and was thus unusable for
