J. Cent. South Univ. Technol. (2008) 15(s1): 402-405 DOI: 10.1007/s11771-008-388-x In-plane shear (ModeⅡ) crack sub-critical propagation of rock at high temperature RAO Qiu-hua(饶秋华), XIE Hai... propagation rate is decreased with the increasing temperature, since high temperature can increase the shear (Mode II) fracture toughness and prevent the crack growth. It is necessary to ensure......

Optimal design of self-propagating high temperature one-dimensional nano-SnO2 synthesisNian LIU and Guodong ZHANG Department of Materials Engineering and Center for Electron Microscopy, Wuhan University, Wuhan 430072, China摘 要:The success in synthesizing high purity SnO 2 nanobelts via self-propagating high temperature synthesis was achieved. According......
and high-textured pyrocarbon can block the crack propagation and change the propagation direction of the main crack, which leads to the higher flexural strength and modulus of C/C composites. Key... by in situ grown CNF, the interfacial layer which consists of CNF and PyC is formed, which conduces the lower crack propagation rate. 3) The CNFs with high strength and modulus can effectively transfer......
