Özet:

Thermoelastic stress response of a periodic heat generating solid cylinder is investigated by analytical means. The cylinder is initially at zero temperature. For times greater than zero, heat is generated internally and slowly at a time dependent rate. Two periodic heat generation rates are used. The temperature distribution in the solid cylinder corresponding to each generation rate is obtained by making use of Duhamel’s theorem. An uncoupled thermoelastic solution of the solid cylinder is then obtained under generalized plane strain condition. The effects of various parameters on the stress and deformation behavior of the cylinder are studied and presented in graphical forms.
