In the case of the limited level density of the material surface energy, the fracture stress and the calculation formula of the engineering damage were studied.
本文研究考虑损伤时材料的断裂应力,推导出了在表面能密度有限的情况下,损伤断裂应力的计算公式。
The threshold stress and fracture stress of hydrogen-induced cracking of X80 pipeline steel are studied by constant load test and slow stain rate test.
The anti fracture stress in each stage of the experiment group was better than that of the control group(P
生物力学测试中,各个阶段实验组抗折应力均优于对照组(P
The local cleavage fracture stress is mainly determined by the length of the critical microcrack.
细观解理断裂应力主要由临界裂纹的长度决定。
The fracture stress of DP microstructure increased with the increase of displacement speed, and the microcrack density increased with the decrease of displacement speed.
双态组织的断裂应力随加载速度的上升而增加,微裂纹面密度随加载速度的增加明显下降;
For fracture rock, the fracture stress will be reduced and the crack length will increase under the chemical corrosion.
对于裂隙巖体来说,化学溶液的腐蚀则主要体现在断裂应力的减小和裂隙的增大。
Temperature impacted on the fracture stress and elastic modulus of the material obviously. Elevated temperature will lead to low fracture stress and smaller elastic modulus.
