Energy bounds for some non-standard problems in thermoelasticity

摘要

A. E. Green (FRS 1958) and P. M. Naghdi developed two theories of thermoelasticity, called type II and type III, which are likely to be more natural candidates for the identification of a thermoelastic body than the usual theory. We here derive energy bounds for a class of problem in which the 'initial data' are given as a combination of data at time t = 0 and at a later time t = T. Such problems are in vogue in the mathematical literature and may he used, for example, to give estimates of solution behaviour in an improperly posed problem where one wishes to continue a solution backward in time.
