Calculation of FLC for high-strength low alloy steel
The mechanical properties and the forming limit curves (FLC) of six different high-strength low alloy steel materials were measured,as well as the key influencing factors to the strain level of FLC were analyzed.It showed that the FLC0 is profoundly related to the thickness and elongation of the materials.Based on the tensile test properties,the empirical formulas for calculating FLC were brought out,which showed better accuracy than the conventional method for quick calculation of the FLC of low alloy sheet metals.
