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 soft materials whose behavior arises from complex polymer-network-fluid interactions. Combining theory and experiments, we show that their mechanics simplif…
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…
Contact point geometry governs structural build-up at rest in Portland cement-limestone blends
Luca Michel, Antoine Sanner, Franco Zunino +2
The early stiffening of fresh cement paste plays a key role in shaping and stability during casting and 3D printing. In Portland cement systems, this phenomenon arises from the for…
Elasticity of bidisperse attractive particle systems
Yaqi Zhao, Antoine Sanner, Luca Michel +1
Bidisperse particle systems are common in both natural and engineered materials, and it is known to influence packing, flow, and stability. However, their direct effect on elastic…
Breaking better: How imperfections increase fracture resistance in architected lattices
Alessandra Lingua, Antoine Sanner, François Hild +1
Fracture behavior in architected materials can be influenced by heterogeneities, yet the mechanisms by which imperfections affect crack propagation remain poorly understood. In thi…
Navigating the Complexities of Multiple Redox State Interactions in Aqueous Systems
Shishir Mundra, Mohit Pundir, Barbara Lothenbach +2
Numerous aqueous systems host elements in multiple redox states, with wide ranging implications such as their influence on the formation/dissolution of minerals, water toxicity, an…
Simplifying FFT-based methods for solid mechanics with automatic differentiation
Mohit Pundir, David S. Kammer
Fast-Fourier Transform (FFT) methods have been widely used in solid mechanics to address complex homogenization problems. However, current FFT-based methods face challenges that li…
Learning Physics-Consistent Material Behavior from Dynamic Displacements
Zhichao Han, Mohit Pundir, Olga Fink +1
Accurately modeling the mechanical behavior of materials is crucial for numerous engineering applications. The quality of these models depends directly on the accuracy of the const…
A thermo-hygro computational model to determine the factors dictating cold joint formation in 3D printed concrete
Michal Hlobil, Luca Michel, Mohit Pundir +1
Cold joints in extruded concrete structures form once the exposed surface of a deposited filament dries prematurely and gets sequentially covered by a layer of fresh concrete. This…
