摘要

研究了非局部连续体模型的主要参数对中心有椭圆切口的板的应力集中的影响，也称为Kirsch问题。描述了介质热膨胀对板的应力-应变状态的影响。并将所得结果与经典结果进行了比较。结果表明，在应力集中区域，最大应力和热流密度减小，应变减小。

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.
