The effect of pin-hole interference and additional stress relieving holes in the plate is investigated. Initial studies were performed on the pin-loaded plate with various crack sizes at the center of the plate, with different interference levels, typical of industrial components. Later, parametric studies were conducted by inserting an additional hole of different diameters placed at a distance from the central cracked hole that acts as stress reliever. The synergistic effect of interference and additional hole in reducing the SIF has been analyzed and the most beneficial interference level, diameter of additional hole and its position has been identified. © 2020 The Authors.

Introduction Fatigue crack propagation has been one of the foremost reasons for the failure of dynamically loaded components. Replacement cost of components with a propagating crack is many times costlier than the methods to repair them. 1.
