Reduction of Stress Concentration in a Plate of Unlimited Dimensions with Angular Notches
Abstract
Reduction in stress concentration in plates angular notches, by modifying the continuity of the notch without changing the radius of curvature, is attempted on the example of a plate of infinite dimensions with a quasi-square hole. For a plate of extended along the Ox axis by uniformly distributed forces, the reduced contour conditions for the opening are mathematically derived, and the maximum stress along the contour is calculated. A reduction in maximum stress by 20% was obtained by optimizing the contour.
