Welcome to the SGMRS Group!
The SGMRS Group in the Department of Civil and Environmental Engineering at IIT Delhi studies the mechanics of materials and structures under extreme loading and uncertainty. Our research focuses on fracture and failure mechanics, high-strain-rate phenomena from ballistic and blast loading, and the design of architected metamaterials.
We also develop methods for inverse problems, combining filtering, optimisation, and uncertainty quantification to infer material behaviour and structural response from data. By integrating mechanics-based theory with advanced computational approaches, we aim to design resilient structures and next-generation engineered materials for challenging applications.
