Rock structures are subjected to cyclic tension-compression loading due to a blasting, earthquake, traffic and injection-production in underground storage case. Therefore study the fatigue behavior of rock samples under this type of loading is required. In this study, the accumulated fatigue damage for a Green Onyx rock sample which consisted of only one mineral composition with two-step high-l...
Fatigue life of Ti alloys is decreased by tensile stress dwell even at room temperature, which called Cold Dwell (CDF). CDF similar to creep-fatigue some metals (stainless steel, Ni-base alloy, and so on) in the point decrease fatigue with or strain high temperature. In this study, time exhaustion rule ductility based on linear cumulative damage were calculated for assessments. case rule, total...
Title of Document: A NON-LINEAR DAMAGE MODEL WITH LOAD DEPENDENT EXPONENTS FOR SOLDERS UNDER SEQUENTIAL CYCLIC SHEAR LOADS Elviz George, Ph.D., 2015 Directed By: Professor Michael G. Pecht, Department of Mechanical Engineering The damage state of a material subject to cyclic loads is often characterized by the cycle ratio of applied cycles to the number of survivable cycles. The damage in a mat...
A general methodology for stochastic fatigue life prediction under variable amplitude loading is proposed in this paper. The methodology combines a nonlinear fatigue damage accumulation rule and a stochastic S–N curve representation technique to achieve this objective. The nonlinear damage accumulation rule proposed in this paper improves the deficiencies inherent in the linear damage accumulat...
Under theenforcing the law on damage, when patients are exposed to damage and injury when acting or leaving action on health-related factors such as physicians and laboratory officials, patients must take standard action to mitigate the loss or claim. Otherwise they will lose the right to defend themselves. The most important effect of this rule is that the assignment of a claim against a loss ...
In this paper, a thermodynamic analysis of Bouc-Wen models endowed with both strength and stiffness degradation is provided. It is based on the relationship between the flow rules of these models and those of the endochronic plasticity theory with damage, discussed in a companion paper (Erlicher and Point, 2007). Using the theoretical framework of that extended endochronic theory, it is shown t...
mental disabled, according to the individual tort system is consider being liable if causes damage to another person. this rule seems not to be fair. in this article two solutions are proposed: first, fault presumption obtained by extensive interpretation of article seven of tort act and second authority conferred to judges by article 7 of the same act. but the just and final solution is the cr...
