Finite element analyis of the reinfoircement of a steel plate with unreinforced concentric circular cutout

Abstract

The necessary cutouts are in a thin-walled structure as functional requirement which weaken the affected part of the structures thus compromising the structure’s integrity. This effect can be reduced by attaching a portion reinforcing the edge of the cutout, so that in the vicinity of the cutout the required strength, vibration and stability requirements are met. This paper is devoted to some issues of the finite element analysis of the reinforcement of the edge of a circular cutout by examining the effect of geometrical parameters and to compare to the values formed in the case of a steel plate with unreinforced concentric circular cutout.
