of the compression fracture, the length range of crack fracture in different stress states was solved, the mathematical expectation of crack length was calculated by probability statistics... coefficient and angle on rock strength. When the friction coefficient is 0, the corresponding angle of minimum strength of rock is 45°. With the increase of the friction coefficient, the crack angle......
Carbide Effects on Creep Crack Growth of Ni-Cr Austenitic Steels祝苏明,朱世杰,王富岗,张俊善摘 要:<正> By controlling the carbon content ofFe-15Cr-25Ni alloys,three types ofmicrostructures were obtained:single phaseaustenite (γ),γ+intergranular carbides,γ+intergranular carbides + intragranular carbides.Creep crack growth behaviour of the three alloyshas been......
Impact Energy of Functionally Graded Steels with Crack Divider ConfigurationAli Nazari,Jamshid Aghazadeh MohandesiDepartment of Mining and Metallurgical Engineering, Amirkabir University.... Charpy impact energy of as-prepared specimens was measured in the form of crack divider. The obtained results show that the impact energy of the specimens depends on the type and the volume fraction......

the Realistic Failure Process Analysis program. With the increase of homogeneity, cracks are concentrating to the ligament area with a decreasing number of crack bifurcations, and the main crack path is becoming smooth. Crack behaviors and mechanical properties are influenced significantly when the homogeneity index is in the range of 1.5 to 5. When the homogeneity index is greater than 30......
