Bio-inspired architected materials and composites:
Behaviour of heterogeneous materials at large deformation regime is extremely intriguing. In order to utilize the heterogeneity in recent years a new type of material has emerged, namely micro/nano architected materials. These are in many cases the result of mimicking biological materials and modern additive manufacturing techniques make it possible to manufacture them.
In our group we are interested to probe the finite deformation behaviour of these materials and structures made of them. We are constantly investigating towards developing the necessary nonlinear thermodynamically consistent model and computational tools to achieve this goal. These materials have potential to radically transform the design of protective structural systems, automobile and aerospace structures and medical implants.
Physics informed Machine learning and Multiscale mechanics:
Bio-inspired composites are intricate and requires 3D printing for production. Constant progress in concrete 3D printing technology may enable construction of efficient next-generation structural components inspired by nature in near future. However, identification and optimization of micro-morphology of such structures requires systematic understanding of their mutiscale behaviour. In this regard, our research focuses on developing efficient computational tools that utilizes the efficiency of modern Deep learning techniques and the multiscale nonlinear physics of the system.
Peridynamics, Phase field fracture and Plasticity:
We are also involved in fundamental investigation of damage and viscoplasticity of crystalline and amorphous materials. Theory of Peridynamics and Phase field approach of fracture play the key role in damage modelling in our work. We intend to develop physics based models consistent with non-equilibrium thermodynamics, in some cases even consistent with generalized Fluctuation theorem.
3D Concrete Printing and structural optimization
We have recently established a modern facility for 3D printing of concrete structures. Our goal is to dive deep into this emerging construction technology and contribute to understanding the rheological characteristics of green concrete, the behaviour of printed structures and design topology optimized concrete structures amenable to printing.
