usually applied. This theory is in good agreement with experiments on ductile
materials such as steel. According to this theory, the equivalent stress may be
calculated from the following formula [42A]:
20: = (Oz - 0,)' + (Ot - 0,)' + (0, - 0,)' + 6 ~ ' (4-54)
where be = equivalent stress in psi
oZ = axial stress in psi (0, > 0 for tension, oZ < 0 for compression)
