Nonlinear Mechanics and Predictable Bifurcation of Multi-Cell Kresling Origami Chains
Songlin Yue, Leo de Waal, David Garcia Cava +1
Meta-structures that display axial-twist coupling can be achieved through the emerging kinematics in Kresling origami patterns. A central challenge in these structures is understan…
How Geometry Tames Disorder in Lattice Fracture
Matthaios Chouzouris, Leo de Waal, Antoine Sanner +3
We investigate the fracture behavior of pre-cracked triangular beam-lattices whose elements have failure stresses drawn from a Weibull distribution. Through a statistical analysis…
Cracking Down on Fracture to Functionalise Damage
Leo de Waal, Matthaios Chouzouris, Marcelo A. Dias
In this work we propose a novel relationship between topology and damage propagation in Maxwell lattices that redefines fracture as a functional design feature rather than mere deg…
Architecting mechanisms of damage in topological metamaterials
Leo de Waal, Matthaios Chouzouris, Marcelo A. Dias
Architecting mechanisms of damage in metamaterials by leveraging lattice topology and geometry poses a vital yet complex challenge, essential for engineering desirable mechanical r…
Cutting holes in bistable folds
T. Yu, I. Andrade-Silva, M. A. Dias +1
A folded disk is bistable, as it can be popped through to an inverted state with elastic energy localized in a small, highly-deformed region on the fold. Cutting out this singulari…
Foldable Cones as a Framework for Nonrigid Origami
I. Andrade, M. Adda-Bedia, M. A. Dias
The study of origami-based mechanical metamaterials usually focuses on the kinematics of deployable structures made of an assembly of rigid flat plates connected by hinges. When th…
Programmed buckling by controlled lateral swelling in a thin elastic sheet
M. A. Dias, J. A. Hanna, C. D. Santangelo
Recent experiments have imposed controlled swelling patterns on thin polymer films, which subsequently buckle into three-dimensional shapes. We develop a solution to the design pro…
