Classical plate theory of thin structures shows how the disk strain-energy can be uncoupled into two components: in-plane extension-compression energy, calculated by noting the relative movement of points in the central plane of the disk (an imaginary plane that halves the disk into two thinner disks); and out-of-plane bending energy that causes curvature changes on the disk surface, but no relative movement of neighboring points in the disk central plane; (19, 20) and the Appendix.
