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.
Faculty in Solid Mechanics
- Predictive, multi-scale modeling and simulation of microstructure evolution in confined granular systems, with an emphasis in manufacturing processes and the relationship between product fabrication and performance.
- Application areas of interest include:
- (i) particulate products and processes (e.g., flow, mixing, segregation, consolidation, and compaction of powders),
- (ii) continuous manufacturing (e.g., Quality by Design, model predictive control, and reduced order models), and
- (iii) performance of pharmaceutical solid products (e.g., tensile strength, stiffness, swelling and disintegration), biomaterials (e.g., transport and feeding of corn stover) and energetic materials (e.g., deformation and heat generation under quasi-static, near-resonant and impact conditions, and formation and growth of hot spots) materials.
- Thermal stresses, thermal fracture and fatigue of advanced materials, in particular high temperature materials, ceramic coatings.
- Mechanical behavior, design and remodeling of biological tissues, effect of stresses on remodeling, microbiomechanics of cell-extracellular matrix (ECM) interactions, tissue engineering
- Contact mechanics
- Stresses, fatigue and friction of rolling/sliding
