Everything else is held at the defaults, including the 3 mm bow across the width. The push acts at a corner for the rectangle and the square and at the rim point opposite the hole for the ellipse and the circle, so part of the difference is the excitation itself: a rim point of an ellipse is stiffer than the corner of a rectangle, and the same 10 mm push deforms the whole sheet rather than bending a corner.",
