Abstract
The influence of the main parameters of the nonlocal continuum model on the stress concentration was studied when solving the problem of stretching a plate with an elliptical cutout in its center, also called the Kirsch problem. The influence of thermal expansion of the medium on the stress-strain state of the plate was studied. The obtained results were compared with the classical ones. It was shown that the maximum stress and heat flux density decrease, and the deformation in the stress concentration zones increases.
