Crack-Tip Opening as a Probe for Length-Scale Separation in Geometrically Nonlinear Solids
Raúl Lazo-Molina, Mokhtar Adda-Bedia, Mohit Pundir +2
Soft elastic solids are highly deformable materials where fracture is driven by the complex coupling of geometric and material nonlinearities. While geometric nonlinearity (GNL) ar…
Hydrogel mechanics below swelling equilibrium
A. Chao Correas, Y. Feng, R. W. Style +1
Hydrogels are versatile materials due to their softness and ability to undergo large changes in water content. Their mechanics, however, are complex, being a tight coupling between…
Element-deletion-enhanced digital image correlation for automated crack detection and tracking in lattice materials
Alessandra Lingua, Arturo Chao Correas, François Hild +1
Architected materials can exhibit remarkable combinations of stiffness, strength, and toughness, yet their application is currently limited by an incomplete understanding of how cr…
A versatile FEM framework with native GPU scalability via globally-applied AD
Mohit Pundir, Flavio Lorez, David S. Kammer
Energy-based finite-element formulations provide a unified framework for describing complex physical systems in computational mechanics. In these energy-based methods, the governin…
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…
Disordered origins, deterministic outcomes: How the architecture of elastic networks imprints relaxed structure and mechanics
Stefanie Heyden, Mohit Pundir, Eric R. Dufresne +1
This work targets the influence of disorder on the relaxed structure and macroscopic mechanical properties of elastic networks. We construct network classes of different types of d…
