Description Of Research Interests

Dr. Surendra Beniwal's research interests are in nondestructive evaluation, focused ultrasound, wave propagation and scattering, modeling of wave propagation in strongly heterogeneous media like concrete and subsurface imaging. The subsurface characteristics of concrete like media are mapped through the application of synthetic aperture focusing (SAFT) and reverse time migration (RTM) techniques using mainly the body waves, and associated ultrasonic signal processing. The subsurface mapping is developed to assist in identifying the defects, damages and bond condition of steel reinforcements in the medium and to give an overall picture of the subsurface. The newly developed interest are in theoretical multiscale modeling (starting from the properties on micro/nano scale) of concrete to evaluate the bulk elastic properties.
