Abstract

The static and dynamic version of the body force analogy of linear thermoelasticity is extended with respect to the following problem: In a dynamic setting, we present a distribution of imaginary forces, such that the isothermal displacements due to the latter are equal to the difference between the thermal displacements due to a prescribed thermal actuation stress and a certain prescribed displacement field.
