Mehdi Omidvar, PhD, is an Assistant Professor in the Civil and Environmental Engineering Department at Manhattan College. He received his PhD from New York University, where he studied the macro and micro scale behavior of natural and artificial sands to rapid penetration. He has published over 30 articles dealing with granular mechanics, soil dynamics, and nonlinear dynamics. Klappentext Rapid Penetration into Granular Media: Visualizing the Fundamental Physics of Rapid Penetration introduces readers to the variety of methods developed to visualize, observe, and model the rapid penetration of natural and man-made projectiles into earth materials while providing seasoned practitioners with a standard reference that showcases the topic's most recent developments in research and application. There has been a flurry of recently funded research both in the U.S. and Europe on studying the behavior of projectiles in granular media. This book compiles the findings of recent research on the subject and outlines the fundamental physics of rapid earth penetration, and assembles a comprehensive collection of experimental and numerical techniques to study the problem.
