J. Casey et S. Krishnaswamy, A CHARACTERIZATION OF INTERNALLY CONSTRAINED THERMOELASTIC MATERIALS, Mathematics and mechanics of solids, 3(1), 1998, pp. 71-89
A new and more primitive treatment of internal constraints for thermoe
lastic materials is presented. integrable strain-temperature constrain
ts are considered and are used to define an equivalence relation on th
e set of unconstrained thermoelastic materials. A unique constrained m
aterial is associated with each equivalence class of unconstrained mat
erials. The properties of the constrained material are inherited from
the unconstrained materials belonging to its corresponding equivalence
class.
