SOME GENERALISATION OF THE EQUATION OF VIRTUAL
The paper presents a global formulation of the initial – boundary problem of coupled thermoelasticity. The principle of virtual work was used. The equation for virtual work in thermoelasticity has been formulated for various types of thermal boundary conditions as well as internal sources of heat. The problem of coupled thermoelasticity in a plane stress state, especially in a rigid disk, is considered in a further part of the paper. In the formulation of the virtual work principle, some changes of the boundary thermal conditions have been considered on a plane bordering the rigid disk, on the assumption that the temperature distribution is symmetrical with respect to the central surface of the rigid disk.
Key words: coupled thermoelasticity, virtual work, rigid disk.
