Narayan Sundaram, PhD
Associate Professor

Welcome

I am an Associate Professor of Civil Engineering at the Indian Institute of Science and am the PI of the Interfacial Solid Mechanics Group.

Our research interests span a broad area that includes contact mechanics, adhesion, indentation, and large strain plasticity in metals processing (deformation processing, machining) with a focus on polycrystalline aggregates. We are also interested in plasticity in cellular and hierarchical solids.

My research group is particularly interested in developing 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 PhD in Aeronautics & Astronautics and MS in Materials Science from Purdue University, and a BTech from IIT Roorkee. Click here or here for my former advisors' webpages.

I taught Solid Mechanics (CE 204), a department core course, from Fall 2014 through 2021. Electives I've taught include CE 284: Plates, Shells, and Geometric Elasticity (Spring 2022, Fall 2023), Plasticity Theory (CE 228) [Spring 2023; 2014-17], and Problems in the Mathematical Theory of Elasticity (CE 297) [Spring 2020-21, Fall 2024]. In Spring 2024, I taught CE 205: Finite Element Method.

Please check back from time to time; this site is updated regularly.
