Correlation between Machine Twist Angle and Unit Twist Angle in Calculating Shear Stresses for Elastic and Plastic Strains in Torsion

Abstract

For a solid torsion bar, the ratio between the unit twist angle and the machine twist angle remains linear, even when the twist shows plastic deformation. Therefore, the torsional stresses may be calculated from a torque- twist curve, whether the twist axis is unit twist angle or machine twist angle. This allows for stress calculations beyond the limit of the unit twist gage.
