MUTUAL INFLUENCE OF COLLINEAR SURFACE CRACKS AND A CIRCULAR HOLE IN THE ISOTROPIC PLATE

摘要

We study the mutual influence of collinear surface cracks and a circular hole on the stress state of an iso-tropic plate. To solve this problem, we use the method of boundary integral equations and the line-spring model. The obtained system of singular integral equations is solved numerically by the method of mechanical quadratures. We also study the influence of various parameters on the concentration of stress-strain state in the plate.
