Fast nastic motion of plants and bio-inspired structures
Qiaohang Guo, Eric Dai, Xiaomin Han +3
The capability to sense and respond to external mechanical stimuli at various timescales is essential to many physiological aspects in plants, including self-protection, intake of…
Shape Selection and Multi-stability in Helical Ribbons
Qiaohang Guo, Anil K. Mehta, Martha A. Grover +3
Helical structures, almost ubiquitous in biological systems, have inspired the design and manufacturing of helical devices with applications in nanoelecromechanical systems (NEMS),…
Mechanics of Tunable Helices and Geometric Frustration in Biomimetic Seashells
Qiaohang Guo, Zi Chen, Wei Li +5
Helical structures are ubiquitous in nature and engineering, ranging from DNA molecules to plant tendrils, from sea snail shells to nanoribbons. While the helical shapes in natural…
Continuum Elasticity Theory Approach for Spontaneous Bending and Twisting of Ribbons Induced by Mechanical Anisotropy
Zi Chen, Carmel Majidi, David J. Srolovitz +1
Helical ribbons arise in many biological and engineered systems, often driven by anisotropic surface stress, residual strain, and geometric or elastic mismatch between layers of a…
Nonlinear geometric effects in mechanical bistable morphing structures
Zi Chen, Qiaohang Guo, Carmel Majidi +3
Bistable structures associated with non-linear deformation behavior, exemplified by the Venus flytrap and slap bracelet, can switch between different functional shapes upon actuati…
