These proceedings contain current research from industry, academia
and government organizations, working on opaque and transparent
ceramic armor. Papers on novel materials concepts for both vehicle
and body armors are included, as well as papers that explore the
relationship between computational modeling and property
testing.
These papers were presented at the Proceedings of the 30th
International Conference on Advanced Ceramics and Composites,
January 22-27, 2006, Cocoa Beach, Florida. Organized and sponsored
by The American Ceramic Society and The American Ceramic Society’s
Engineering Ceramics Division in conjunction with the Nuclear and
Environmental Technology Division.

Om författaren
Andrew A. Wereszczak received his Ph.D. in Materials Science
& Engineering from the University of Delaware in 1992, and
while his research is varied, the study and interpretation of the
relationship between mechanical properties and microstructure (of
monolithic ceramics, structural materials, and electronic
materials) are common denominators. Micromechanical
characterization of structural and armor ceramics using
instrumented static and dynamic indentation (e.g., Hertzian) with
acoustic emission analysis, and adapting those measured
performances and damage mechanism analyses to strength, rolling
contact fatigue, wear, machining, and ballistic performances is a
primary objective.
Additionally, ceramic strength and fatigue testing, ceramic
fractographical and flaw population analyses, Weibull analysis
strength-size-scaling, and probabilistic life prediction and design
of structural ceramic components constitutive another primary
research objective. In support of all these efforts, both
conventional and microstructural-level finite element stress
analyses and microstructure characterization are performed. He is
the author or co-author of over 100 technical publications and has
given over 80 presentations, and is the co-developer of
µ-FEA software.
Edgar Lara-Curzio is a Distinguished Research Staff
Member and the leader of the Mechanical Properties and Mechanics
Group at Oak Ridge National Laboratory. Since 1999 he has
been serving as leader of the Mechanical Characterization and
Analysis User Center in ORNL’s High Temperature Materials
Laboratory. Lara-Curzio received a B.Sc. degree in
Engineering Physics from the Metropolitan University in Mexico City
in 1986 and a Ph.D. in Materials Engineering from Rensselaer
Polytechnic Institute, Troy NY, in 1992.
His research work has been focused on studying the mechanical
behavior, durability and reliability of structural and functional
materials, on understanding the relationships among their
processing, microstructure and properties, studying the effect of
service environment on their properties and on developing models to
describe their behavior and to predict their service life.
Dr. Lara-Curzio has co-edited 6 books and has authored 4 book
chapters and more than 140 publications in refereed journals and
conference proceedings.
