Expression for Calculating Plastic Radius, c, from Slit Opening of a Disk from an Autofrettaged Tube

Abstract

Prior research gives good estimates of the autofrettage plastic radius for a range of gun tube conditions and material strengths. A linear fit of a portion of these results gives an expression here for the plastic radius of a partially autofrettaged tube, with accurate results for tube outer radius to tube inner radius, b/a near 2.0 and degree of autofrettage near 50%, configurations of common use with autofrettaged gun tubes. These results are presented here and compared with finite element calculations from autofrettaged gun tubes.
