A hole in a plate, optimal for its biaxial extension - compression
An outline of a hole of equal strength in an elastic plate loaded at infinity by mutually perpendicular tensile and compressive forces, is obtained. It is shown that under these conditions the hole is bounded by a contour with corners, and its form is found by numerical methods. It turns out that the contour is very close to rectangular, with slightly rounded sides, whose ratio depends on the load.
