About
Dr. Srivastava received his Ph.D in materials science and engineering from the University of North Texas in 2013, and his undergraduate degree in mechanical engineering from the Kamla Nehru Institute of Technology in Sultanpur, India. His research interests include micromechanical modeling of heterogeneous materials, microstructure-based crystal plasticity element modeling, phase transformations, quantifying constitutive behavior of metals by small scale experiments, in-situ mechanical testing, failure analysis and microstructure design.
