Long description
This figure shows a side-on view of a rectangular plate with a hole in it. The hole diameter is about a third of the width of the plate, the width being the shorter of the two rectangular dimensions. At one end of the plate is an extension on one of the long sides. The extension is of square shape and the length of its sides is about one fifth of the longer length of the rectangle. Superimposed on the plate is a mesh of about 220 rectangular elements mostly of square shape, 16 of them on the square extension piece. The elements around and near the hole are somewhat distorted from the ideal square shape.
