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…
Grain and Grain Boundary Segmentation using Machine Learning with Real and Generated Datasets
Peter Warren, Nandhini Raju, Abhilash Prasad +5
We report significantly improved accuracy of grain boundary segmentation using Convolutional Neural Networks (CNN) trained on a combination of real and generated data. Manual segme…
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…
Effect of Sintering Temperature on Microstructure and Mechanical Properties of Molded Martian and Lunar Regolith
Peter Warren, Nandhini Raju, Hossein Ebrahimi +4
Cylindrical specimens of Martian and Lunar regolith simulants were molded using a salt water binder and sintered at various temperatures for comparing microstructure, mechanical pr…
Coupled Bend-Twist Mechanics of Biomimetic Scale Substrate

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
