Abstract

Previous results on bounding the energy dissipation of bodies which creep have been extended to include plastic deformations. The theorems, which are derived, show that previous results can be used, provided the stress fields which are selected nowhere exceed the value of the ratio n/n + 1 of the yield condition for stress.
