Dr. Narayan Sundaram
Assistant Professor

IISc Logo



I am an Assistant Professor in the Department of Civil Engineering at the Indian Institute of Science.

My research interests lie in a broad area that is best termed "interfacial solid mechanics", including contact mechanics, adhesion, indentation, and large strain plasticity in metals processing (deformation processing, machining) with a focus on polycrystalline aggregates. I am also interested in non-standard continua and computational plasticity.

The recent efforts of my research group include a push to develop enabling tools (solvers, meshers) to aid first-in-class simulations in some of these areas.

Prior to joining IISc, I was a Postdoctoral Research Associate at the Center for Materials Processing and Tribology, Purdue University. I hold a Ph.D in Aeronautics & Astronautics and MS in Materials Science from Purdue, and a BTech from IIT Roorkee. Click here or here for my advisors webpages.

I teach Solid Mechanics (CE 204) in Fall and taught Plasticity Theory (CE 228) in Spring 2014-17.
