BOUNDS ON THE RATE OF ENERGY DISSIPATION IN BODIES DEFORMING BY SECONDARY CREEP.
Abstract
The present note extends previous methods of bounding the rate of energy dissipation in a body deforming under secondary creep according to a power law (strain-rate tensor = b signa to the n power). By an appropriate definition of the 'representative stress', bounds for a material with an arbitrary value of n are expressed in terms of a postulated known solution to the identical stress loading problem for a material with a different value of n. The results are applied first to idealised materials where n is a constant, and then extended to a class of non-idealised materials where n is a monotonic increasing function of stress. (Author)
