Wide beam, or when is the beam a plate? The bending stiffness of a beam with rectangular cross-section (h x b) is D=Eh3b/12 with E=Young's modulus. If the width b is large, the beam deflects like...

Kirsch's celebrated 1898 problem gives the stress in points A and B at a circular hole in the infinite plate. For the finite plate a formula for the stress in point A is given in books. I am...
