Analytical and Finite Element Analysis of Thermal Autofrettage process in Spherical vessel
The mechanism of thermal autofrettage is described in relation to the more common mechanical autofrettage. This paper provides analytical and FE analysis of thermal autofrettage process has been conducted for spherical vessel considering von Mises yield criterion to predict behavior within the plastic zone. Elastic-plastic stress distribution subjected to thermal load are evaluated. This study include residual stress prediction on an uniaxial loading-unloading stresses of elastic perfectly plastic material model. Feasibility of Centrifugal and Centripetal autofrettage are discussed and compare.
