brittle fracture initiation的意思|示意

Fracture mechanism, initiation and propagation of cracks, and the control method of cracks in rock like brittle material under dynamic load are described in this paper.

本文主要论述了动荷载作用下岩石等脆性材料的断裂破坏机理、裂纹形成与扩展以及裂纹的止裂与控制等内容。

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。
