Dennis Coon , Professor of Mechanical EngineeringUniversity of Wyoming College of Engineering Department of Mechanical Engineering
Prof. Coon was born and raised in the rolling hills of the Finger Lakes region in New York State. He received a BS in Ceramic Engineering in 1980 from the New York State College of Ceramics at Alfred University. From 1980 through 1981 he was employed as a ground coat development engineer in the R&D laboratory of Mobay Chemical's Pemco Products Division in Baltimore. He attended graduate school in the Materials Science Department of the Pennsylvania State University from 1982 through 1985, and received an MS (1984) and PhD (1986) in Ceramic Science. His MS research work concentrated on mechanical properties of oxynitride glasses, and PhD research work examined the effect of atomic structure on subcritical crack growth in oxide glasses. From 1986 through 1988 he was a Senior Research Scientist in the structural ceramic group at the Idaho National Engineering Laboratory. Prof. Coon was involved in research on processing and properties of oxynitride glasses and advanced joining techniques for nitride and carbide ceramics, and was a member of the team awarded an IR 100 Award for Ceramic Joining in 1988. Since 1988, Prof. Coon has been on the faculty of the Mechanical Engineering Department at the University of Wyoming. During his time at the University of Wyoming, his research has involved properties of oxynitride glasses, processing and properties of SiAlONs, mechanical properties of ceramic matrix composites, reliability of ceramics, and Monte Carlo modeling methods.
Damage Modeling and Reliability of Ceramic Matrix Composites
Many crack models currently in use are 2-D models of material behavior. Unfortunately, materials response in application is three-dimensional. The purpose of this project is to modify 2-D crack growth models to simulate 3-D failure in ceramic matrix composites. This research is an opportunity for a graduate student with a background in materials science, engineering mechanics, and computational techniques.
Application of Monte Carlo Modeling to Engineering Systems
Monte Carlo models are the combination of stochastic characteristics of engineering systems and deterministic models of system behavior. Relatively complex can be conveniently modeled by Monte Carlo methods, and both typical and unique system behaviors can be predicted. This research is an excellent opportunity for a graduate student with a background in materials science, applied statistics, and computational techniques.
