Brush-mediated angular constraints reshape structure, rigidity, and percolation in colloidal depletion gels

Colloidal gels, like many other soft and disordered solids derive their mechanical properties not only from the strength of interparticle attraction but also from the symmetry of the forces that constrain particle motion. Although noncentral interactions are known to profoundly a...

Non-local physics-informed neural networks for forward and inverse solutions of granular flows

Abstract Dense granular flows exhibit nonlocal effects due to stress transmission in microplastic events, especially in quasi-static or slowly sheared regions. Hence, traditional local rheological models fail to capture spatial cooperativity effects that are prominent in many gra...
