At present, his group is investigating temperature-dependent plastic deformation and stress corrosion cracking behavior of high entropy alloys.
Although we are interested in investigating a wide range of mechanical properties, our current research focus is shown schematically in Figure 1. We are currently investigating following characteristics of different metallic materials: stress corrosion cracking, friction stir welding and processing, and room temperature to high temperature plastic deformation behavior.
Dr. Kumar focuses on establishing correlation among processing , microstructure, and mechanical properties in metallic materials used in transportation and power-generation industries.
My current research works include fracture mechanics based study of stress-corrosion cracking of austenitic stainless steel, creep, and creep-fatigue study of next-generation stainless steel. I am also investigating biaxial creep deformation behavior of Zr-base alloy for nuclear fuel cladding. In the past, I have worked on a wide variety of alloys used in aerospace, automotive, and marine industries.
