On size effect of mechanical properties of thermoelastic solids
In this paper the principal relations of a thermoelastic solid model for the local gradient approach in thermomechanics are presented. Within the framework of such an approach the stationary stressed-strained state of a stretched isotropic thermoelastic layer is examined. On this basis using the com...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | In this paper the principal relations of a thermoelastic solid model for the local gradient approach in thermomechanics are presented. Within the framework of such an approach the stationary stressed-strained state of a stretched isotropic thermoelastic layer is examined. On this basis using the common meaning of elasticity modules the size effects of Young’s modulus, Poisson’s ratio and bulk modulus are studied. The isotropic quality of elasticity modules size effects is confirmed. It is shown that in the considered model the shear modulus does not depend on the specific size (thickness) of the layer. The numerical results are presented as graphs. |
