Numerical Analysis of Thin Plates with Holes

Abstract

Plates are the important structural members finding applications in the field of structural engineering, ship technology and aerospace engineering. Holes are often provided in the plates for the purpose of services and aesthetics. Pitting corrosion can also induce holes on the plates, thereby inducing stress concentration and redistribution of stress around the hole. In this paper, the popular finite element software ANSYS is used for the static analysis of thin plates with holes. The influence of shape and size of the hole on the stress distribution of plate is also analysed. The study can form foundation for strength assessment of steel plates with holes, especially residual strength of plates subjected to pitting corrosion.
