The thermomechanical foundations of the field of doublet mechanics are introduced. the present approach utilizes the concepts of energy and entropy balance to derive thermodynamic restrictions on the governing equations of the theory. The constitutive assumptions of nonlinear elastic doublet mechanics are analyzed. Further restrictions on the material response functions are determined from consideration of superposed rigid body motions. Finally, the equations of the nonlinear elastic case are linearized and presented in simplified form.
