Abstract

The fact that standard specimens made of high-strength bearing steel undergo spall fracture during quasi-static tension is experimentally proved. The uniqueness of this fracture consists in the fact that it proceeds due to the elastic energy of the specimen, in contrast to the classical spallation during high-speed collision or a high-energy pulsed external action. High-speed video filming is used to demonstrate that the mode I fracture of a specimen and its subsequent spall fracture are spaced in time.

准静态拉伸过程中高强钢的散裂断裂

摘要

用高强度轴承钢制成的标准试件在准静态受拉过程中发生剥落断裂的事实已得到实验证明。这种断裂的独特性在于它是由于试样的弹性能量而进行的，这与高速碰撞或高能脉冲外部作用期间的经典散裂形成对比。高速视频拍摄用于证明试样的 I 型断裂及其随后的剥落断裂在时间上是间隔开的。
