.... This in turn requires optimization of autofrettage pressure [ 3 ]. Since the autofrettage process is affected by loading–unloading cycle of plastic deformation the analysis of autofrettage process requires the calculation of Bauschinger effect factor [ 4 ]. The first analytic model of autofrettage process...
