ductile crack

常见例句

The crack growth process is a continuous process of alternating crack-tip stretching and ductile crack cracking.
裂纹的增长过程是一个裂纹尖端延伸与延性裂纹启裂持续地交替出现的过程。
For precraked specimen , the elevation of normal stress ahead of the ductile crack is related to the stress intensification and the strain hardening.
对于裂纹试样，裂尖前端正应力升高是由于应力强化和应变强化这两个因素决定的。
Fracture test of the BT20 indicates that brittle unstable fracture occurs after ductile crack initiation and slow propagation for all the compact tension (CT) specimens.
BT20 钛合金断裂试验表明，CT 试样均在裂纹延性启裂并缓慢扩展后，发生脆性失稳断裂。
