Bending Mechanics of Biomimetic Scale Plates
Pranta Rahman Sarkar, Hossein Ebrahimi, Md Shahjahan Hossain +1
We develop the fundamentals of nonlinear and anisotropic bending behavior of biomimetic scale plates using a combination of analytical modeling, finite element (FE) computations, a…
Anisotropic plates with architected tendon network
Md Shahjahan Hossain, Hossein Ebrahimi, Ranajay Ghosh
We synthesize geometrically tailorable anisotropic plates by combining button shaped fish-scale like features on soft substrates, then lacing them with high-stiffness strings. This…
Material-Geometry Interplay in Damping of Biomimetic Scale Beams
Hossein Ebrahimi, Milos Krsmanovic, Hessein Ali +1
Biomimetic scale-covered substrates are architected meta-structures exhibiting fascinating emergent nonlinearities via the geometry of collective scales contacts. In spite of much…
Coupled Bend-Twist Mechanics of Biomimetic Scale Substrate
Sanjay Dharmavaram, Hossein Ebrahimi, Ranajay Ghosh
We develop the mechanics of combined bending and twisting deformation of a one-dimensional filamentous structure with protruding stiff fish-scale-like plates embedded at an angle o…
Coulomb friction in twisting of biomimetic scale-covered substrate
Hossein Ebrahimi, Hessein Ali, Ranajay Ghosh
Biomimetic scale-covered substrates provide geometric tailorability via scale orientation, spacing and also interfacial properties of contact in various deformation modes. No work…
Frictional Damping in Biomimetic Scale Beam Oscillations
Hessein Ali, Hossein Ebrahimi, Ranajay Ghosh
Stiff scales adorn the exterior surfaces of fishes, snakes, and many reptiles. They provide protection from external piercing attacks and control over global deformation behavior t…
Tailorable Twisting of Biomimetic Scale-Covered Substrate
Hossein Ebrahimi, Hessein Ali, Ryan Alexander Horton +3
In this letter, we investigate the geometrically tailorable elasticity in the twisting behavior of biomimetic scale-covered slender soft substrate. Motivated by our qualitative exp…
Tailorable Elasticity of Cantilever Using Spatio-Angular Functionally Graded Biomimetic Scales
Hessein Ali, Hossein Ebrahimi, Ranajay Ghosh
Cantilevered beams are of immense importance as structural and sensorial members for a number of applications. Endowing tailorable elasticity can have wide ranging engineering rami…
Bending of Biomimetic Scale Covered Beams Under Discrete Non-periodic Engagement
Hessein Ali, Hossein Ebrahimi, Ranajay Ghosh
Covering elastic substrates with stiff biomimetic scales significantly alters the bending behavior via scales engagement. This engagement is the dominant source of nonlinearity in…
