摘要:
Parabola density and radius is shown to decrease as the testing temperature increases. Furthermore, both the density and radius of the parabolas depend on their position on the fracture surface: their magnitude decreases as the distance from the notch increases. Finally, a criterion for parabola formation based on two mechanisms, plastic flow activation and craze initiation, is discussed.
