Finite indentation of highly curved elastic shells
Experimentally measuring the elastic properties of thin biological surfaces is non-trivial, particularly when they are curved. One technique that may be used is the indentation of a thin sheet of material by a rigid indenter, while measuring the applied force and displacement. This gives immediate information on the fracture strength of the material (from the force required to puncture), but it...
متن کاملCorrugated Structures and Their Applications in Morphing Wing Technology
This paper will explore the technology behind corrugated model morphing wings and their potential benefits to society. The two major models of corrugated morphing wings will be examined and explained. In order to provide background, the technology and shape behind all morphing wings will also be examined. The applications of these wings will then be explored. Using data from wind tunnel testing...
متن کاملBuckling Analysis of Axially Loaded Corrugated Cylindrical Shells
Buckling analyses of heavily corrugated cylindrical shells based on detailed full finite element models are usually computationally expensive. To address this issue, we have proposed an efficient computational method of predicting the onset of buckling for corrugated cylindrical shells which builds on the Bloch wave method for infinitely periodic structures. We modified the traditional Bloch wa...
متن کاملDeformation and failure of curved colloidal crystal shells.
Designing and controlling particle self-assembly into robust and reliable high-performance smart materials often involves crystalline ordering in curved spaces. Examples include carbon allotropes like graphene, synthetic materials such as colloidosomes, or biological systems like lipid membranes, solid domains on vesicles, or viral capsids. Despite the relevance of these structures, the irrever...
متن کاملGeometrically controlled snapping transitions in shells with curved creases.
Curvature and mechanics are intimately connected for thin materials, and this coupling between geometry and physical properties is readily seen in folded structures from intestinal villi and pollen grains to wrinkled membranes and programmable metamaterials. While the well-known rules and mechanisms behind folding a flat surface have been used to create deployable structures and shape transform...
