Prakash Sarkar

Currently, I am working as an Assistant Professor in the Metallurgical and Materials Engineering department at National Institute of Technology (NIT) Jamshedpur, India.

My research interests center on understanding how materials deform at small length scales, with a particular focus on nanoindentation as a tool for probing localized mechanical behavior. I am especially interested in glassy polymers and polymer nanocomposites, where molecular architecture, interfacial interactions, and nanoscale confinement can dramatically influence properties such as hardness, modulus, and time-dependent deformation. In parallel, I study the mechanical response of soft metals and alloys, aiming to uncover how microstructure, strain rate, and temperature affect their plasticity and yielding under small-scale contact loading. By integrating experimental nanoindentation techniques with structure–property analysis, my work seeks to develop design principles for advanced materials with tailored mechanical performance. 

My research keywords: Nanoindentation, Glassy polymers, Polymer nanocomposites, Soft metals and alloys.
