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, integrators) 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.

The core courses I've taught include CE 204: Solid Mechanics, for eight years from Fall 2014 through Fall 2021, and CE 205: Finite Element Method in Spring 2024, 2025 and 2026. Electives I've taught include CE 284: Plates, Shells, and Geometric Elasticity [Spring 2022, Fall 2023], CE 228/228N: Plasticity Theory [Spring 2023; 2014-17; Fall 2025], and Problems in the Mathematical Theory of Elasticity (CE 297) [Spring 2020-21, Fall 2024].

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