Hervé Le Dret, Annie Raoult
We show that the Oldroyd B fluid model is the Eulerian form of a Lagrangian model with an internal variable that satisfies the second law of thermodynamics under some conditions on…

A few remarks on thermomechanics
Hervé Le Dret, Annie Raoult
We develop a global setting for modeling thermo-visco-elastic materials that satisfy the principles of thermodynamics and are properly invariant. This setting encompasses many know…
