Abstract

Abstract By means of the application of a yield criterion, according to which yielding takes place when that part of the stress-work which is conserved reaches a definite maximum value, it is shown that from the constitutive equation of anelasticity two phenomena follow. On one hand, when the load is constant, yielding can take place after some time in creep. On the other hand, when a constant rate of strain is applied, the yield stress increases with the rate of strain.
