Fracture mechanism, initiation and propagation ofcracks, 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。
2
The voids affect the initiation and propagation ofcracks under the hygrothermal circumstance.
孔隙在湿热环境下影响了裂纹的产生与扩展。
3
The initiationof the cracks was caused by stress corrosion resulting from the co-effect of the corrosive gas dust and the axial tensile stress.
