A Closed-form Solution for the Kinematics of Asymmetric Miura Vertices
Soroush Kamrava, Chang Liu, Alec Q. Orlofsky +2
The Miura vertex is a versatile origami pattern found in a variety of mechanisms. Previous papers have derived and validated a closed-form solution for the kinematics of a symmetri…
Multi-material Topology Optimization of Lattice Structures using Geometry Projection
Hesaneh Kazemi, Ashkan Vaziri, Julian A. Norato
This work presents a computational method for the design of architected truss lattice materials where each strut can be made of one of a set of available materials. We design the l…
Computational Modeling of the Effects of Inflammatory Response and Granulation Tissue Properties on Human Bone Fracture Healing
Mohammad S. Ghiasi, Jason E. Chen, Edward K. Rodriguez +2
Bone healing process includes four phases: inflammatory response, soft callus formation, hard callus development, and remodeling. Mechanobiological models have been used to investi…
Slender Origami with Complex 3D Folding Shapes
Soroush Kamrava, Ranajay Ghosh, Yu Yang +1
One-dimensional slender bodies can be deformed or shaped into spatially complex curves relatively easily due to their inherent compliance. However, traditional methods of fabricati…
Origami-inspired Cellular Metamaterial with Anisotropic Multi-stability
Soroush Kamrava, Ranajay Ghosh, Zhihao Wang +1
Origami designs offer extreme reconfigurability due to hinge rotation and facet deformation. This can be exploited to make lightweight metamaterials with controlled deployability a…
Frictional Effects in Biomimetic Scales Engagement
Ranajay Ghosh, Hamid Ebrahimi, Ashkan Vaziri
Scales engagement can contribute significantly to nonlinear bending behavior of elastic substrates with rigid biomimetic scales. In this letter, we investigate the role of friction…
Wrinkling reveals a new isometry of pressurized elastic shells
Dominic Vella, Hamid Ebrahimi, Ashkan Vaziri +1
We consider the point indentation of a pressurized, spherical elastic shell. Previously it was shown that such shells wrinkle once the indentation reaches a threshold value. Here,…
Type-IV Pilus Deformation Can Explain Retraction Behavior
Ranajay Ghosh, Aloke Kumar, Ashkan Vaziri
Polymeric filament like type IV Pilus (TFP) can transfer forces in excess of 100pN during their retraction before stalling, powering surface translocation(twitching). Single TFP le…
Persistence of a pinch in a pipe
L. Mahadevan, A. Vaziri, Moumita Das
The response of low-dimensional solid objects combines geometry and physics in unusual ways, exemplified in structures of great utility such as a thin-walled tube that is ubiquitou…
Curvature condensation and bifurcation in an elastic shell
Moumita Das, Ashkan Vaziri, Arshad Kudrolli +1
We study the formation and evolution of localized geometrical defects in an indented cylindrical elastic shell using a combination of experiment and numerical simulation. We find t…
