brittle fracture test的意思|示意

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。

In this paper, Based on the theory analysis and test, the fracture mechanism and fracture direction of brittle materials are studied.

本文主要通过理论分析和试验，对脆性材料的断裂机理及断裂方向进行研究。

After low temperature test, the sample does not appear breaks or brittle fracture.

光纤槽道能承受低温试验。 试验后，试样不产生裂痕或脆断；

After the stated conditions of aging, impact test, the sample doesn't crack or brittle fracture.

光纤槽道能承受规定条件下的老化、冲击试验。试验后，试样不产生裂纹或脆断；
