crack extension

常见例句

The stress corrosion mechanism in mixed solutions was studied based on the metallographic observations of scanning fracture shapes and crack extension direction.
根据扫描断口形貌和裂纹扩展途径的金相观察，还探讨了在混合溶液中的应力腐蚀机制。
Only if this short crack extends long enough and blunted wide enough, can it affect the principal crack extension and the distribution of stress and plastic strain.
只有小裂纹扩展到足够长并钝化到足够宽，才能够影响主裂纹的扩展及其前端应力、应变的分布。
The outlined models for estimation of crack extension angles rely purely on the stress intensity factors at the crack tip which can be determined by finite element procedures.
用这些模型预测裂纹扩展角时，参数都归结为裂尖处的应力强度因子，而应力强度因子可以用有限元方法求得的。
