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.
