The category of problems which examines the mechanical behaviour of contact regions constitutes an important branch of applied mechanics with extensive engineering applications. The results of such research can be applied to the study of mechanics of composite materials, tribology, soil-foundation interaction, mechanics of rock interfaces, modelling of damage phenomena and micro-mechanics. In classical studies, the modelling of interface responses has focussed on purely idealized forms of interface phenomena which range from frictionless contact to bonded contact, with Coulomb friction or finite friction occupying an intermediate position. Current research has attempted to improve such modelling by endowing the interface with its own characteristic constitutive responses. This research indicates the significant manner in which non linear, frictional, dilatant, hardening and softening interface constitutive responses can influence the global and local interface responses of engineering interest.
The technical sessions held in New Mexico (sponsored by the Elasticity Committee of the Engineering Mechanics Division of the American Society of Civil Engineers) brought together new advances in the theoretical formulation, analysis and the application of material interface modelling to problems of engineering interest. This book contains the papers presented plus invited contributions from leading researchers.

George Z. Voyiadjis is the Boyd Professor at the Louisiana State University, in the Department of Civil and Environmental Engineering. This is the highest professorial rank awarded by the Louisiana State University System. He joined the faculty of the University of Louisiana State University in 1980. Voyiadjis’ primary research interest is in damage mechanics of metals, metal matrix composites, and ceramics with emphasis on the theoretical modeling, numerical simulation of material behavior, and experimental correlation. Dr. Voyiadjis’ research has been performed on developing numerical models that aim at simulating the damage and dynamic failure response of advanced engineering materials and structures under high-speed impact loading conditions.
He has over 164 referred journal articles and 14 books (8 as editor) to his credit. Over forty graduate students (21 Ph. D.) completed their degrees under his direction. He has also supervised eleven postdoctoral associates. Voyiadjis has been extremely successful in securing more than $8.0 million in research funds as a principal investigator from the National Science Foundation, the Department of Defence, the Air Force Office of Scientific Research, the Department of Transportation, and major companies such as IBM, and Martin Marietta.
He has been invited to give theme presentations and lectures in many countries around the world. He has also been invited as guest editor in numerous volumes of the Journal of Computer Methods in Applied Mechanics and Engineering, International Journal of Plasticity, Journal of Engineering Mechanics of the ASCE, and Journal of Mechanics of Materials. These special issues focus in the areas of damage mechanics, structures, fracture mechanics, localization, and bridging of length scales. He is currently a Fellow in the American Society of Civil Engineers, the American Society of Mechanical Engineers, and the American Academy of Mechanics.
