Abstract: In order to solve the coupled thermoelastoplastic problems by the finite element method, it is necessary to establish suitable functional. In this paper, based on the thermoelastoplastic constitutive relation proposed by K.N. Rysinko and E.I. Blinov[1], the functional of coupledthermoelastoplasticity is derived by means of the nonlinear functional analysis theory.
