摘要: In order to investigate the mechanical properties of small TC4 titanium alloy specimens under high stress state, a U-shape notched small punch test and its corresponding simulation were carried out. Meanwhile, the influence of the friction coefficient, specimen thickness, the diameter of the hole, and the punch rate on the calculated results were also discussed. The results showed that upon increasing the specimen thickness and punch rate, the peak load obtained by calculations increased as well. The void volume fraction and …
