An Orthotropic Membrane Model for the Large Deformation Analysis and Snapping Phenomena of the Dome Inflated

Abstract

Abstract. The paper proposes a method to enable analyzing any large deformation of membrane structures. If the analysis uses even very small rigidity against compression in the structures, the computation becomes multi-bifurcated problem and unstable. The original compression-free model used in the method keeps the structures in tension field and this makes computing the deformation always very stable. The paper uses the advantage of the method and shows a snapping phenomenon during constructing a membrane dome. Though the snapping phenomenon is not so public, the phenomenon occasionally happens in the construction site and it causes the destruction.

Dynamic Modeling and Structural Optimization of a Bistable Electromagnetic Vibration Energy Harvester

“…In related researches on the vibration of membranes, many studies are the small-amplitude vibration of membranes [39,40]. For the large deflection of membranes, the general researches consider the deformation of membranes under different loads, which belongs to the static problem [41][42][43]. However, there has been little research considering the large-amplitude vibration response of membranes with co-axial mass.…”
