Abstract

There are two basic forms of equation relating the steady-state creep rate, epsilon , to the applied stress, sigma , with the stress incorporated either as sigma **n or as ( sigma minus sigma //o)**n degree where n and n//o are the appropriate stress exponents and sigma //o is a threshold or friction stress. The implications of these two relationships are examined and it is demonstrated that, although there are a range of values for (n,log//1//0A) lying on straight lines which may have different slopes for different materials, all lines pass through a unique point given by (n//o,log//1//0A//o) equal to (3,0), where A and A//o are the dimensionless constants in the two different equations for epsilon . It is concluded that there is a universal creep equation with a third power stress dependence which applies to all crystalline materials in the power-law creep regime.
