I am a Postdoctoral Researcher in the Department of Aerospace and Mechanical Engineering at the University of Arizona. I received my B.Tech.-M.Tech. dual degree in Aerospace Engineering from the Indian Institute of Technology (IIT) Kanpur in 2012 and Ph.D. degree in Aerospace Engineering from the University of Arizona in 2022.
Prior to Ph.D., I worked as a structural analysis engineer at General Electric-Aviation, Bengaluru and as a research engineer at IIT Kanpur. I also worked at Idaho National Laboratory as a summer visiting scholar in 2018 and 2019.
I have extensive experience in the field of theoretical and computational solid mechanics with an emphasis on failure analysis and peridynamics. I am currently conducting research in the area of molecular dynamics, optimization, and uncertainty quantification.
Education:
Ph.D., The University of Arizona, Tucson, AZ (2022)
Thesis: Peridynamics for Failure Prediction in the Presence of Material Nonlinearity and Finite Deformation [link]
B.Tech-M.Tech (Dual Degree), Indian Institute of Technology Kanpur, India( 2012)
Thesis: Investigation of interfacial fracture toughness of unidirectional fiber composites using DCB technique [link]
Peridynamics introduced by Silling [1] is a non-local continuum theory based on the postulation that interaction between material points occur over a finite distance. The approach is extremely suitable in modeling crack initiation, propagation and their complex interactions.
This book discusses recent advances in peridynamics modeling. The theme of the book is based in non ordinary state based peridynamics and comes with codes for numerical examples.

Peridynamic prediction of failure in styrene butadiene rubber with multiple cutouts
The video shows the failure in rubber sheet with multiple cutouts. The simulation is performed using non-ordinary state based peridynamics using implicit technique. The code is written in Fortran with Intel Pardiso solver.
