Architected materials are nature inspired modern man-made materials with unprecedented properties.

We have been actively working to develop fundamental understanding of the finite deformation characteristics of such materials. In process we have developed generalized continuum based multiscale approach to investigate their large deformation including that of local buckling induced instability.

It is of great interest to probe the fundamental aspects of damage of these materials to enable their use in real life applications.

Peridynamics is a reformulation of Continuum mechanics in terms of integro-differential equation. Most important aspect of this formalism is its capability to handle spontaneously emerging and propagating crack automatically without any external enrichment.

We are actively involved to derive Peridynamics formulations for several generalized solids and structures (like plate, shell) and investigate their fracture behaviour.

Plasticity and damage are intricate and irreversible process. They originate from the activities of microscopic defects like dislocation, void, micro-cracks etc.

Getting rid of the oft-used phenomenological theories, we focus on developing Physics based two-temperature theories for modelling plasticity and damage in metals and polymers.
