The effect of stiffening on the stress concentration in a flat plate with a hole

摘要

This research was on the effectiveness of stiffeners fastened on either side of a hole or cutout in a flat plate loaded in tension for reducing stress concentrations at the edge of the cutout. Stress data has been compiled from sixteen flat plate geometries having various hole diameter-to-plate width ratios. Each plate was modeled using an analysis solftware package and solved without stiffening, and then with stiffeners located at various distances from the hole.
