Autofrettage is a method for increasing fatigue strength of components for use at high and pulsating pressures. In short, Autofrettage compresses a container’s inner surface, making better use of the material’s structural properties. The process can reduce fatigue concerns in pulsating applications and lets engineers reduce tubing thickness in high-pressure applications without sacrificing strength, life, or safety. The autofrettage method is based on the reciprocal relationship of the plasticized inner zone and the elastically deformed outer zone. The components are placed under so much pressure that their interiors become plastically deformed. After relaxing, pressure stresses are created in these areas, which prevent the outer areas from reforming to their original shape. Instead, it remains stretched. This prevents crack formation in the later application, increases the service life of
