coupling, plastic non-isothermal yielding theory, finite element method, stresses, optimization.

Within the plastic non-isothermal yielding theory the elastic-plastic thermal stresses has been investigated in a connective unit formed by means of thermal coupling shrinkage on tubes to be connected. The mathematical model for description of the thermomechanical processes has been proposed. The applicable mechanics problem has been formulated. The approximate approach for its solving based on the finite element method has been realized. The optimization of the coupling profile with variable thickness in axial direction has been fulfilled. A search of the optimal coupling variant has been executed for profiles restricted by piece-wise linear surfaces. The optimization criterion by minimization of inequality of normal contact pressure  distribution has been proposed.
