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…
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…
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…
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…
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…
Frictional contact between solids: A fully Eulerian phase-field approach
Flavio Lorez, Mohit Pundir
Recent advancements have demonstrated that fully Eulerian methods can effectively model frictionless contact between deformable solids. Unlike traditional Lagrangian approaches, wh…
