brittle crack propagation的意思|示意

Brittle fracture. Fracture that occurs by rapid crack propagation and without appreciable macroscopic deformation.

通过快速裂纹扩展发生断裂，没有明显的宏观变形。

This paper presents a theoretical analysis about the propagation rule of the micro-crack in brittle materials under axial compression, based on the energy release rate criterion.

本文利用混合型裂纹扩展的能量释放率理论对脆性材料受轴向压缩时其内部微观裂纹的扩展规律进行了研究。

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.

BT 20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。
