Abstract

In this paper a metallic plate made of steel with an elliptical hole, having fixed long radius and variable short radius is pressure loaded. A comparison is made between the results obtained from analytical equations (from reference 16) for a plate with an elliptical hole and the results obtained from FEA. To show that increasing the order of the element can be one way to improve the results obtained from FEA model two different finite elements (4 node and 8 node plane element) were used on the model. This was shown by measuring the length of the element at the tip of the ellipse. It is possible to produce a more accurate FEA model by increasing the number of elements in a mesh. To show this, the number of elements used to mesh the model were recorded and compared for each ellipse size.
