About Me Welcome to my webpage! I am a PhD student in the Department of Metallurgical and Materials Engineering at the Indian Institute of Technology Madras, Chennai, India. Under the guidance of Prof. Anand K. Kanjarla, I conduct my research at the Laboratory for Mechanics of Microstructures, IIT Madras. I have a passion for mathematics and programming, which drives my enthusiasm for working in computational mechanics. Currently, I am exploring phase-field modelling of fracture in polycrystals and its implementation using the scaled boundary finite element method. Research Interests -  Scaled boundary finite element method
-  Phase-field modelling of fracture
-  Crystal plasticity

Computational study of initiation and propagation of cracks in metallic materials Prof. Anand Krishna Kanjarla
Laboratory for mechanics of microstructures,
Dept. of Metallurgical and Materials Engineering, IIT Madras.
Jul 2022 - Present
  • The aim is to develop a numerical framework that combines phase-field modelling with crystal plasticity using the scaled boundary finite element method to simulate nucleation and propagation of cracks in metallic materials.
  • The developed framework will be used to understand the effect of microstructural features on crack nucleation and propagation in metals.
