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…
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…
Precipitation of corrosion products in macroscopic voids at the steel-concrete interface -- observations, mechanisms and research needs
Shishir Mundra, Emanuele Rossi, Luka Malenica +2
Macroscopic voids at the steel-concrete interface and their degree of saturation with an aqueous electrolyte are known to play an important role in the corrosion of steel in reinfo…
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…
The key to the enhanced performance of slab-like topologically interlocked structures with non-planar blocks
Ioannis Koureas, Mohit Pundir, Shai Feldfogel +1
Topologically interlocked structures are assemblies of interlocking blocks that hold together solely through contact. Such structures have been shown to exhibit high strength, ener…
Eulerian framework for contact between solids represented as phase fields
Flavio Lorez, Mohit Pundir, David S. Kammer
Mechanical contact between solids is almost exclusively modeled in Lagrangian frameworks. While these frameworks have been developed extensively and applied successfully to numerou…
Transonic and supershear crack propagation driven by geometric nonlinearities
Mohit Pundir, Mokhtar Adda-Bedia, David S. Kammer
Linear elastic fracture mechanics theory predicts that the speed of crack growth is limited by the Rayleigh wave speed. Although many experimental observations and numerical simula…
An FFT-based framework for predicting corrosion-driven damage in fractal porous media
Mohit Pundir, David S. Kammer, Ueli Angst
Understanding fracture in cementitious materials caused by the deposition and growth of corrosion products requires scale-bridging approaches due to the large length-scale differen…
