Dynamic Behavior of Brittle Materials
When: July 31- August 1, 2014
Instructor: Ghatu Subhash, PhD, Knox T. Millsaps Professor, UF Research Foundation Professor, Mechanical and Aerospace Engineering, University of Florida
Location: Johns Hopkins University, Homewood Campus, Baltimore, MD
About the course:
The course presents a range of fundamental issues in dynamic response of brittle materials with emphasis on the relationship between material selection, properties and performance in dynamic applications. It is mainly aimed at entry level graduate students, engineers, and researchers with interest in applications of ceramics to rapidly applied loads. The contents of the course are as follows:
- Brief history of applications of ceramics
- Introduction to the light-weight ceramic system for dynamic applications, relevance of material properties, importance of material selection, mechanisms in confined ceramics, various phases of evolved damage during dynamics loading, and the effect of confinement on dynamic ceramic behavior.
- Dynamic testing methods (phenomenological, design oriented, and material characterization approaches)
- A review of the fundamentals of wave propagation, dynamic fracture, and high strain rate experimental methods
- Characterization methods along with spectrographic methods
- Modeling of impact response of ceramics including mechanistic-based and statistical-based approaches.
- The effects of confinement on brittle fracture, fragmentation, and communition.
- Impact response of transparent materials (sapphire, AlON, Spinel, strengthened glasses and others), damage propagation characteristics, stress wave interactions, and fragmentation processes
- Future demands, requirements, and technological pathways for development of light-weight ceramic materials and systems
