PROBLEM OF COUPLED THERMOELASTICITY
The paper presents a problem of coupled thermoelasticity in elastic rigid disks. To solve this problem, two numerical methods have been applied. First of all, a finite elements method was used and as result of it the set of ordinary differential equations with regard to a time variable was obtained. This set of equations was solved with the second numerical method – SSpj method. On the basis of carried out calculations, short qualitative analysis of the influence of the field of strains and temperature coupling on generation and character of displacements, stresses and temperature fields was determined.
Key words: coupled thermoelasticity, rigid disk, finite elements method, Zienkiewicz-Wood?s (SSpj) method.
