Solid Mechanics   

While a textbook definition of Solid Mechanics is simply the study of the behavior of solid materials, the breadth of this field is enormous, as are the implications for material science, manufacturing, biomedicine, and much more. At Purdue, we study solid mechanics from the macro to the micro: from the tiniest atoms at Birck Nanotechnology Center, to the powders, particles, pharmaceuticals, and foodstuffs analyzed at the Center for Particulate Products and Processes (CP3), the most comprehensive particle lab in all of academia.
