A theoretical and experimental study of thermal autofrettage process

Abstract

Thick walled cylinders hollow disks find wide range of industrial applications to withstand very high pressure Pressure vessels gun barrels fuel injection system in diesel engines nuclear reactor and fastener holes are the typical examples The cylinder may crack if the working internal pressure exceeds the yield strength of the material The pressure carrying capacity and fatigue life of the thick walled cylinders used for high pressure application can be significantly improved by inducing
