About the Laboratory

Shock waves are generated during hypervelocity meteoritic impacts and explosions. While traversing through a solid medium, the shock waves impart plastic deformation. Depending upon the characteristics of the medium and the shock waves, the deformation ranges from fracturing, pulverization, polymorphism, melting to vaporization. Led by Dr. Amar Agarwal, we investigate this deformation. We use standard techniques such as field studies, microstructural analysis, spectral studies and magnetic investigations (induced and remanent). This is coupled with various innovative investigative techniques like high-speed deformation experiments, mathematical modelling and hydrocode simulations. Refer to our latest publications and projects for more information.
