A variational physics-informed graph neural network for heterogeneous solid mechanics
Aashay Rajan Yadav, Amiya Prakash Das, Ratna Kumar Annabattula
Stress localization in heterogeneous solids is governed by the bimaterial interface, where the displacement field remains -continuous, while in-plane stresses jump due to the…
Hybrid Surrogate-Based Multi-Objective Optimization of Graded BCC Lattices
Jaswanth V Gurudev, Ratna Kumar Annabattula
Functionally graded BCC lattice structures hold promise for applications requiring simultaneous impact absorption and thermal dissipation, yet existing optimization frameworks rely…
Hydrodynamic Behavior of Non-spherical Particles in Confined Vertical Flows: A Resolved CFD-DEM Study
Amiya Prakash Das, Shakti Swaroop Choudhury, Sujith Reddy Jaggannagari +4
We investigate the sedimentation and vertical hydraulic transport of non-spherical polymetallic nodules (PMNs) using resolved computational fluid dynamics-discrete element method (…
Optimized mouldboard design for efficient soil inversion using the discrete element method
Vinay Badewale, Sujith Reddy Jaggannagari, Prasad Avilala +1
The design of a mouldboard (MB) plough is critical for achieving efficient soil inversion, which directly impacts soil aeration, weed control, and overall agricultural productivity…
A DEM-driven machine learning framework for abrasive wear prediction
Prassana Chandan, Amiya Prakash Das, Shakti Swaroop Choudhury +1
Particle-induced wear is a critical concern in bulk material handling systems, where abrasive interactions accelerate equipment degradation, increase maintenance needs, and raise o…
Study of triaxial loading of segregated granular assemblies through experiments and DEM simulations
Venkata Rama Manoj Pola, Ratna Kumar Annabattula
A simple position-dependent body force-based confinement for simulating triaxial tests using the Discrete Element Method is presented. The said method is used to perform triaxial s…
