In this paper experimental and theoretical FLD and FLSD of AA3105 are investigated. For this purpose, the forming limit diagram of Aluminum alloy 3105 using out‐of‐plane test is evaluated experimentally. Also, base of emphasis of forming limit stress diagrams and using plasticity equations, the stress limits resulted from strain limits and then forming

Prediction of Forming Limit Diagram with Damage Analysis
SAE Technical Paper Series, 1996<div class="htmlview paragraph">Based on the theory of damage mechanics, an orthotropic damage model for the prediction of forming limit diagram (FLD) is developed. The conventional method of FLD used to predict localized necking adopts two fundamentally different approaches.

Analysis of forming limit diagram for superplastic materials
The International Journal of Advanced Manufacturing Technology, 2005Superplastic materials show very large tensile elongation (in excess of 5000%) even if they are lowly stressed. Superplastic forming is carried out at high temperatures and relatively low strain rates. In order to control the industrial forming processes, the difficulty in predicting the failure strain of superplastic materials is main problem faced by

In this work, the Marciniak and Kuczynski model (MK) will be reviewed and will be generalized to a more general approach for the calculation of forming limit diagrams. In the new model we will account for all directions of the imperfection. This new approach has been used to calculate the theoretical FLDs (forming limit diagrams) for Vonmises, Barlat ...

Forming Limit Diagram Prediction of Stainless Steels Sheets
SAE Technical Paper Series, 2007<div class="htmlview paragraph">The development of adapted design tools, such as Forming Limit Diagrams (FLD), participates to the increasing use of stainless steels in automotive applications notably. FLD are now in widespread use, but still present the major drawback of a test-intensive determination procedure.

Limitations of the M-K Based Forming Limit Diagrams
2012Using a rate dependent Taylor type crystal plasticity formulation, the limitations of Marciniak-Kuczynski (M-K) approach to numerically simulate the Forming Limit Diagrams (FLDs) were studied. Three uniaxial stress-strain curves with three different post-necking hardening behaviors were generated using crystal plasticity formulation.

Forming limit diagram for Indian interstitial free steels
Materials & Design, 2006In this work, the suitability of interstitial free steel sheets of thickness 0.6 and 1.6 mm for press forming operations were examined by obtaining the forming limit diagram. The microstructural aspects, tensile properties and formability parameters were studied.

Determination of warm forming limit diagram for ZEK100
AIP Conference Proceedings, 2013The formability of a rare-earth alloyed magnesium sheet, ZEK100, is studied through determination of its Forming Limit Diagram (FLD). Limiting dome height experiments were performed at elevated temperatures with in situ digital image correlation (DIC) measurement of strain.

Artificial Neural Network Modeling of Forming Limit Diagram
Materials and Manufacturing Processes, 2011Forming limit diagram (FLD) provides the limiting strains a sheet metal can sustain whilst being formed. In this article, the formability of Ti6Al4 V titanium alloy and Al6061-T6 aluminum alloy sheets is investigated experimentally using hydroforming deep drawing.
