Summary

This volume contains papers presented at The Sixth Conference on the Fractography of Glasses and Ceramics held June 5-8, 2011 in Jacksonville, Florida. Papers deal with a variety of ceramics (silicon nitride, alumina, nanocomposites, laminates, dental ceramics, ceria, and zirconia), and glasses. Topics include effects of laser etching of glass, fractography of ion-exchange-strengthened glass, mixed-mode failure, effects on crack evolution and propagation, quantitative fractography, ballistic damage, and effects of processing on strength and fracture behavior. Four invited papers give in-depth coverage of the history of the fractography of glasses and ceramics, phenomena at the crack tip during slow crack growth in glasses, failure and damage mechanisms in ceramic nano composites, and inherent strength and damage mechanisms in glasses. This text provides an excellent one-stop resource for understanding the most important current issues in the research and applications of fractography of glasses and ceramics.

Author Biography

James R. Varner is the Kruson Distinguished Professor of Ceramic Engineering at the Kazuo Inamori School of Engineering, New York State College of Ceramics at Alfred University. He teaches courses in mechanical properties of glasses and ceramics, mechanics of materials, and optical microscopy of materials. Research and professional interests include strength testing, understanding influences on strength, hardness, fractography, stresses, and processing influences on mechanical properties. He received his Ph.D. in Ceramics from Alfred University and is a Fellow of The American Ceramic Society, a member of the German Society of Glass Technology, serves as Committee Chair for the International Commission on Glass, Technical Committee 6, and is a member of the National Institute of Ceramic Engineers.
