Residual Stress in Swage Autofrettaged Cylinders with Axial Semi-Circular Mid-Wall Cooling Channels.
Abstract
ABAQUS finite element modeling and experimental residual stress mapping have been performed for several swage autofrettaged compound cylinders with semicircular mid-wall cooling channels. The experimental results verified most features of ABAQUS-predicted stress distributions, except near the bore and at the channel roots, where significantly reduced compressive residual stresses were observed. These observations have been attributed to reverse yielding effect in these areas.
