Research Interest

Dr. Kumar’s research work encompasses the development of novel magnetoelectric composites with enhanced magnetoelectric output achieved via configurational advancement, formulation of analytical and numerical models to predict the composite behavior, and use the developed composites for device prototype fabrication. Some of the notable contributions of Dr. Kumar include the development of a novel epoxy-free fabrication procedure termed a press-fit method, a novel distributed disc structured (DDS) magnetoelectric composite configuration, and a thermally stable multi-directional magnetic field sensor. Currently, Dr. Kumar is interested in investigating applied mechanics-based shock-wave interaction with smart materials and polymers and studying the impact of high strain rate loading on such materials. These studies would be beneficial in developing materials capable of sustaining impact loads and have extensive applications in defense equipment and armored gears.
