Estimating fatigue strength in components and assemblies is a frequent engineering task. Doing so is critical to judging a component's durability for both its operational life and that of the ...

Autofrettage is an established process in which controlled plastic deformation is induced in the inner layers of thick-walled cylinders to create beneficial compressive residual stresses. This ...

Cold expansion is an established mechanical process that introduces beneficial compressive residual stresses around engineered holes, thereby enhancing the fatigue life of structural components. This ...

EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...

This is a preview. Log in through your library . Abstract Surface mechanical attrition treatment (SMAT) consists of producing a thin surface layer of compressive residual stresses that prevents crack ...

Stress is defined as the force per unit area. Thus, the formula for calculating stress is: Where σ denotes stress, F is load and A is the cross sectional area. The most commonly used units for stress ...

Battery dendrites are not caused by electrical origins, but instead have mechanical sources. The dendrites propagate due to fracture of the electrolyte and subsequent crack filling-in. Stresses on the ...
