Research on the Forming Limit Diagram Based on Laser Shock Forming

Applied Mechanics and Materials, 2010
Laser shock forming (LSF) of sheet metal is a novel technology in plastic deformation. It is necessary to correctly predict the Forming Limit Diagram (FLD) based on LSF. New failure maximum thickness reduction rate criterion is used to determine the forming limit based on the numerical system during LSF. The relationship model between maximum thickness

Application of the forming limit stress diagram to forming limit prediction for the multi-step forming of auto panels

Journal of Materials Processing Technology, 2007
Abstract The strain-based forming limit diagram (FLD) is generally obtained on the linear (proportional) or near linear loading condition. So it often leads to erroneous assessments on the analysis of metal sheet formability under complex strain paths such as multi-step forming by the FLD criterion.

Forming limit diagram generation with reduced experiments and modelling for different grades of automotive sheet steel using CrachLab

Journal of Strain Analysis for Engineering Design, 2017
Forming limit diagram is one of the most commonly used failure criteria for sheet metal forming analysis. Forming limit diagram generation is time-consuming, and therefore, any reduction in the test requirements will be useful for the industry.

Calculation of the forming limit diagram

Metallurgical Transactions A, 1989
A mathematical model is presented to help understand sheet metal deformation during forming. The particular purpose of this model is to predict the forming limit diagram (FLD). The present model is an extension of a previous analysis by Jones and Gillis (JG)[1] in which the deformation is idealized into three phases: (I) homogeneous deformation up to ...

Forming Limit Stress Diagram Prediction of Aluminum Alloy 5052 Based on GTN Model Parameters Determined by In Situ Tensile Test

Chinese Journal of Aeronautics, 2011
The conventional forming limit diagram (FLD) is described as a plot of major strain versus minor strain. However, FLD is dependent on forming history and strain path.
