“…Huang T et al [ 11 ] used GTN damage model parameters obtained by finite element reverse calibration to build simulation models to plot FLD and FLSD which was in good agreement with the experimental results. Yuan S et al [ 12 ] transformed the experimentally obtained limit strain into limit stress by Hill’48 yield criterion and plotted the FLSD of low temperature alloy sheet.…”

The Forming Limit Stress Diagram (FLSD) can accurately describe the forming process of high-strength steel. However, obtaining FLSD is relatively difficult. In order to predict fracture in advanced high-strength dual-phase (DP) steels, limit maximum and limit minimum principal strains of sheet were obtained through multiple sets of test and simulation. Two material parameters, strength coefficient K and hardening exponent n are introduced into the FLSD function which is established by the strain-stress transformation function. The function shows that the k-value determines the value of the maximum principal stress, while the n-value affects the curvature of the curve. Verification of correctness by testing and simulation to within 10% accuracy. This paper explores a new approach to FLSD research based on material properties, which can expand the application scope of FLSD.

“…One of the key issues of formability prediction is determining the strain distribution just before the fracture of the failed specimen [ 19 ]. While several visual tools have been used historically to measure local strain variations, digital image correlation (DIC) is becoming the standard [ 20 , 21 , 22 , 23 ].…”

The formability of aluminum alloy 5754-O tailor-welded blanks prepared by friction stir welding was studied experimentally. The strain evolution and deformation during limiting dome height experiments were studied using digital image correlation and the ARAMIS software. The influence of the sheet thickness of the base materials on the punch loading, fracture strain and formability were investigated experimentally. It was found that the punch loading, fracture strain and limiting dome height values increase with the increasing sheet thickness of the base materials. A linear relationship between the limiting dome height value and the sheet thickness was demonstrated. An increase of 16.8% in the fracture strain of aluminum tailor-welded blanks was observed for an increase of 36% in sheet thickness. This paper provides a methodology for experimentally determining the forming limits of aluminum alloy tailor-welded blanks accurately.
