First-Order Compatible-Strain Mixed Quadrilateral Finite Elements for 2D Nonlinear Elasticity
Mohsen Jahanshahi, Damiano Pasini, Arash Yavari
Compatible-strain mixed finite elements (CSMFEs) use the differential complex of nonlinear elasticity to construct discretizations that preserve the underlying topological structur…
Homogenization framework for rigid and non-rigid foldable origami metamaterials
Xuwen Li, Amin Jamalimehr, Mathias Legrand +1
Origami metamaterials typically consist of folded sheets with periodic patterns, conferring them with remarkable mechanical properties. In the context of Continuum Mechanics, the m…
Temperature-induced shape morphing of bi-metallic structures
Semih Taniker, Paolo Celli, Damiano Pasini +2
In this work, we study the thermo-mechanical behavior of metallic structures designed to significantly change shape in response to thermal stimuli. This behavior is achieved by arr…
Durable Bistable Auxetics Made of Rigid Solids
Xiao Shang, Lu Liu, Ahmad Rafsanjani +1
Bistable Auxetic Metamaterials (BAMs) are a class of monolithic perforated periodic structures with negative Poisson's ratio. Under tension, a BAM can expand and reach a second sta…
Hydro-Responsive Curling of the Resurrection Plant Selaginella lepidophylla
Ahmad Rafsanjani, Véronique Brulé, Tamara L. Western +1
The spirally arranged stems of the spikemoss Selaginella lepidophylla, an ancient resurrection plant, compactly curl into a nest-ball shape upon dehydration. Due to its spiral phyl…
Bistable Auxetic Mechanical Metamaterials Inspired by Ancient Geometric Motifs
Ahmad Rafsanjani, Damiano Pasini
Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual negative Poisson's ratio well suited for designing shape transforming metamaterials. Curr…
