Abstract

Washizu’s principle for stresses, displacements, and strains in isothermal elasticity is extended to the field of coupled thermoelasticity. All field equations, including solid and thermal strain-displacement relations, are deduced from the extended functional. The relation to other known theorems is discussed.
