Reinforced Circular Cutouts in Plane Sheets

Abstract

This investigation is concerned with the problem of the reinforcement of cutouts in plane sheets. Such cutouts may serve either to make a structure lighter or to provide space for personnel or accessories. The problem of designing a reinforcement ring around the cutout so that it will be elastically equivalent to the portion of the sheet removed is treated here by an inverse method. The treatment is given first in general terms and then applied in detail for several types of edge loading. A test was made on a plane sheet with a reinforced cutout to check the effect of some of the simplifying assumptions on the formulas developed.
