Abstract
Creep tests were made with 0.14 percent carbon steel at 450°C under the periodic stresses changing stepwise between two stress levels, the mean stress of which was 17.0 kg/mm2 and the stress amplitudes of which were 1.0 and 2.0 kg/mm2. If was found that, under the test conditions in this study, creep strain under varying stresses could be predicted from the results of constant stress creep tests employing the assumption of the "mechanical equation of state in solid", within an error not exceeding ten percent. The limitations of the "mechanical equation of state in solid" as an approximate method of estimation of the strain under varying stresses were also discussed on the basis of the authors' theory of plastic deformation of metals at high temperatures, in which the effect of stress and temperature history is taken into account.
