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 ...

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 ...

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 ...
