Mixed methods and reduced integration for the circular arch problem
The boundary-value problem for linear elastic circular arches is studied. The governing equations are based on the Timoshenko-Reissner-Mindlin hypotheses. The problem is formulated in both the standard and mixed variational forms which include a parameter relating to the thickness of the arch. …

Analysis of a circular arch by the Rayleigh-Ritz method
… for the analysis of a single-span, pin-connected circular arch subjected to uniform load along the arch. The method is explained, equations for deflections and moments are developed and the results of an illustrated problem are tabulated. The illustrated problem is also solved by a conventional …

Equilibrium of a shallow arch subjected to PZT actuators and a deadweight load
… geometrically nonlinear response of a shallow, circular, cylindrical panel under a midspan line load and induced strain actuation is presented. The panel is a laminate of piezoelectric material perfectly bonded to the convex and concave surfaces of a core of passive material. Since the curved …

Analysis of Pressurized Arch-Shells
A pressurized arch-shell structural component made of flexible material is considered. The component is inflated with high internal pressure. The behavior of similar types of structures, such as a pair of leaning pressurized arches and pressurized arch-supported membrane shelters, has been …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
… unique challenges, and designers constantly search for innovative ways to increase efficiency. One way to save space and reduce cost is to use ortho-planar compliant mechanisms which can be made from sheets of material, or lamina emergent mechanisms (LEMs). This thesis presents principles which …
