Evaluation of Circumferential Mechanical Properties of Tubular Material by Flaring Test

The investigation into the circumferential mechanical properties of tubular materials has been receiving increasing attention, since tube hydroforming process used in forming field, because have a significant effect on hydroformability materials. In present study, method for evaluation with flaring test was proposed. expressions yield stress, strain hardening coefficient and exponent values were successfully derived based geometrical relationships test. To verify reliability this method, calculated results values, obtained from newly proposed compared to ones conventional tensile tests. It found that current study is reliable, high accuracy. appropriate evaluate
