Boʻcopa Во" exp The average creep strain rate in the steady-state regime can be expressed as de Q dt RT where s, t, Bo, Q. T and Rare strain, time, constant, stress, creep activation energy, temperature and gas constant of 8.314 ) moll K 1, respectively. The creep strain rate measured at 2300 °C and stress of 2 MPa is 1 x 10-65 2. Increasing the stress level to 7 MPa whilst maintaining the condition at the identical temperature, the strain rate now is 1 x 10 451 Determine the stress exponent n. The creep activation energy is assumed to be identical for both stress levels.
