Buckling limit diagrams (BLDs) of interstitial free steels (IFS): Comparison of experimental and finite element analysis

In this paper, a modified Yoshida buckling test is presented as an improved and more reliable buckling test in order to determine the buckling limit diagrams (BLDs) of IFS when ranking the formability of sheet metals. The finite element analysis (FEA) is carried out for the modified Yoshida buckling test and compared with the experimental results.
