In this paper, we analyze a pair of shallow arches that are interconnected with each other through their ends by a revolute joint.The other ends of the arches may be pinned or fixed.The two arches have opposite curvature.When one of the arches is subjected to a transverse load, it deforms and eventually flips to its inverted shape.Simultaneously, the deformation of the first arch triggers the switching of the second arch due to a moment transfer between the two arches through the revolute joint, and the second arch flips to its inverted shape too.These arches can be switched back to their as-fabricated shape by applying a transverse load to the second arch.In this way, these connected arches move up and down to take the load at any instant when the switching loads come from a long moving rigid wedge.The motivation to study such connected flipping arches arose from the intent to develop dynamically self-offloading footwear for diabetics suffering from peripheral neuropathy.The purpose of this is to limit the plantar pressure to stay below a prescribed value to prevent ulceration.When a certain region of the sole is offloaded, the array of connected arches helps certain other region to take up the differential load to support the body weight.In this paper, we present a theoretical formulation for two connected arches, solve them semi-analytically, and compare with the results of the geometrically nonlinear finite element analysis.
