Sudip Kunda graduated with a bachelor’s degree in Civil Engineering at the Birla Institute of Technology and Science, Pilani, and worked for a year as a trainee engineer at Wadia Techno-Engineering Services in Kolkata. He earned a master’s degree in Civil Engineering with a specialization in Structural Engineering from the Indian Institute of Science, Bangalore in 2019. He joined UW-Madison in the fall of 2019 and is an Engineering Mechanics Ph.D. student. He is working on capturing the effect of grain size on the flow stress of metal polycrystals. The theory he is developing is applicable to grains whose size is of the order of a few to tens of micrometers. The aim is to replace the empirical inverse square root law from the Hall-Petch effect that is currently in common use, with a theory in which the effect of grain size on flow stress is an emergent phenomenon.

Courses Taught: EMA 202, Dynamics

Noah Schmelzer received his B.A. in Applied Physics from St. John’s University of Collegeville, MN in the spring of 2019 and joined the University of Wisconsin as an Engineering Mechanics Ph.D. student in the fall semester of 2019. He is developing a thermodynamically consistent ductile damage model for better predictability of void-based damage during dynamic loading. He is also investigating the effect of grain boundary character on the nucleation of voids.

Courses Taught: EMA 201, Statics

Akhilesh Pedgaonkar is currently a PhD student in Engineering Mechanics. He has done his B.Tech. in Mechanical Engineering from Indian Institute of Technology, Bombay and M.S. in Mechanical Engineering from University at Buffalo. He has also worked at Hero MotoCorp Ltd. and Ansys, Inc. before joining UW Madison. He is currently working on deformation twinning induced plasticity in pure Titanium. Deformation twinning is an important mechanism of plasticity in HCP materials. His work involves explicit computational representation of deformation twinning with coupled thermodynamics of plasticity.
