Some peculiarities of construction of algorithms to solve 2D-problems of thermoelasticity and thermoelastoplasticity by method of local variations are discussed. While solving thermoelastoplasticity problems the method of local variations is used in combination with the method of varied parameters of elasticity. A peculiarity of the suggested method is application of the finite-element technology at the stage of determination of components of deformation and stress tensors. An example of solving a thermoelastoplasticity problem is considered for a pipe under condition of internal pressure and temperature field.
