Abstract :
Equations for infinitesimal incremental fields superposed on finite biasing fields in a thermoelectroelastic body are derived from the nonlinear equations of thermoelectroelasticity. The equations are general in the sense that no assumptions are made on the biasing fields. The general equations obtained are reduced to various special cases under different approximations.
