Welcome to my page! The website is focused on my research work.
I am Mahendaran Uchimali. I defended my doctoral thesis in computational solid mechanics at the Indian Institute of Technology Madras, India. I am currently working as an assistant professor in the school of mechanical sciences at the Indian Institute of Technology Bhubaneshwar.
I am interested in studying the evolution of microstructures (grains, twins, cracks) and their influence on the macroscopic response (stress-strain behaviour) of materials. At the neighbourhood of the evolving microscale features (crack tip, propagating ledge), the dynamic effect and emitting dispersive waves play an important role on macroscale response. These dynamic microscale effects are significant even for quasistatic applied loads. Description of materials as clusters of interacting particles gives a fascinating insight into their behaviours and these microscale effects.
Towards this, I have developed a novel discrete particle method to describe materials with evolving microstructures. I have studied a few paradigmatic problems involving a material undergoing structural phase transformations. The emphasis is on the influence of martensite morphology and ledge on the stress-strain response of shape memory alloys.
The formulation of the model and its applications are shown with sufficient details on this page and you are welcome for suggestions and collaboration!
