The scheme for the solution of the coupled problem of friction units thermoelastichydrodynamics is given. It is noticed that one of the main ways for decreasing labor input of the task solution may be the choice of the rational finite element providing decision accuracy at a big aspect ratio. Twenty-nodal three-dimensional finite element is chosen and in this finite element not only second order joint shape functions but also the third order out-of-node not joint shape functions are used. By using some test examples for temperature, elastic and thermoelastic problems the advantages of such quasi-joint finite elements in comparison with joint ones are shown.
