Abstract

In this study, investigation is carried out to determine the effects on the stress concentration around a cut-out due to reinforcement around the cut-out in a flat plate and a cylindrical shell, subjected to axial and bending loads. The study is further extended, to a flat plate and a cylindrical shell, subjected to compressive load, containing two identical cut-outs along the length to determine the effect on the stress concentration factor, with the variation of the distance between the cut-outs. This study assumes the use of homogeneous, isotropic material. The investigation is carried out using the FEA software package, ANSYS APDL Mechanical. Parametric study is carried out to understand the variation of the stress concentration. Mathematical relations are also established that relate the diameter of the cut-outs to the distance between them at which they cease to influence one another, in a non-dimensional format.
