ABSTRACT
If aerr and €err are related by £* =8(0'*)", then the stress distribution in multiaxial tension can be calculated. If the stress distribution is known, then the creep rate can be calculated. The equations for creep rates are given by [202,203]
~ =8(0'*)"-1[0'2 - 0.5(0'3 + 0'1)] £3 =8(0'*)"-1[0'3 - 0.5(0'. + 0'2)] (16)
The quantities B and n are determined from the steady-state part of the uniaxial creep test.
