SOLUTION TO A PROBLEM OF STRESS-STRAIN STATE OF A PLATE WITH AN ELLIPTICAL CUT UNDER MECHANICAL AND TEMPERATURE LOADS IN A NONLOCAL FORMULATION

Effect of the main parameters of a nonlocal continuum model on stress concentration is studied when solving a problem of tension of a plate with an elliptical cut at its center, also known as the Kirsch problem. The effect of thermal expansion of the medium on the stress-strain state of the plate is described. The results obtained in this study are compared with the classical results. It is shown that there is an decrease in maximum stress and heat flux density, as well as a decrease in the strain in the stress concentration regions.
