Abstract:

Hoop residual stresses in a right circular steel cylinder were determined by ultrasonic velocity measurements. The zero stress position was obtained from an equilibrium condition, setting the integrated tensile equal to the integrated compressive hoop stress. Absolute stress values were obtained with the help of calibration measurements on a rectangular test bar of the same material, which was subjected to known applied forces. The stresses determined from these ultrasonic velocity measurements are in good agreement with values obtained by x-ray diffraction analysis of lattice strains.
