The importance of true fracture strain was initially highlighted in the context of local versus global formability considerations used in material selection among advanced high strength steels (AHSSs) of similar tensile strength. Inspired by the relative studies, a precedent work compared the fracture ...
The characteristics of creep deformation and time to failure of deep hard rock are important for predict time-dependent disasters. Based on the short-term compression and long-term single-stage creep tests under true triaxial stresses, the characteristics of creep deformation and time to failure of ...
In the context of fracture mechanics, Andrews27 showed, in his theoretical study of an infinite inelastic lamina containing a crack, that the inelastic deformation has a significant role in the total energy change due to crack propagation. Early studies attempted to extend the analytical formula of...
1.what is the formula for brake work per cycle? Three circles of radius R are drawn such that each touches the other two. A fourth circle of radius r, is drawn so that it passes through the points of contact of the larger circles. Determine the rat The pressure ...

Based on the fractal characteristic of concrete material, the relation between fracture toughness and height of crack zone is analyzed. 23. 44kb 介绍了适于混凝土材料的离散单元模型的破坏准则、计算方程以及弹簧系数等计算参数的确定方法。 The failure criterion, formula and determination of analytical par...
According to formula (1)–(3), the stress-balance diagram of the boundary material under the condition of static-dynamic-coupling loading can be obtained, as shown in Figure 5b. It can be observed that the value of each point on the transmission-stress curve coincides with the sum of the...
METHODS OF DETERMINATION OF FRACTURE STRENGTH OF THIN DIAMOND-LIKE COATINGS BY DIAMOND INDENTER.Tests of diamond-like coating were carried out by methods of instrumented indentation and scratch tests for determination of conditions of cracks formation of various types. The comparison of different methods...
Even so, much new knowledge is required to develop stress/strain/time/temperature relationships which accurately define the behaviour of creep‐resistant alloys under the complex non‐steady operating conditions encountered in service.WilshireDepartmentB.DepartmentEBSCO_AspStrength Fracture & Complexity...
