This book provides in a single and unified volume a clear and thorough presentation of the recent advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory. In addition, some sections contain new material that has not appeared before in the literature. The book is divided into three major parts: Part I deals with the scalar formulation and is limited to the analysis of isotropic damage in materials; Parts II and III deal with the tensor formulation and is applied to general states of deformation and damage. The material appearing in this text is limited to plastic deformation and damage in ductile materials (e.g. metals and metal matrix composites) but excludes many of the recent advances made in creep, brittle fracture, and temperature effects since the authors feel that these topics require a separate volume for this presentation. Furthermore, the applications presented in this book are the simplest possible ones and are mainly based on the uniaxial tension test.
Part I Isotropic damage mechanics - scalar formulation: uniaxial tension in metals; uniaxial tension in elastic metal matrix composites; uniaxial tension in elasto-plastic metal matrix composites - vector formulation of the overall approach. Part II Anisotropic damage mechanics - tensor formulation: damage and elasticity in metals; damage and plasticity in metals; metal matrix composites - overall approach; metal matrix composites - local approach; equivalence of the overall and local approaches; metal matrix composites - local and interfacial damage; symmetrization of the effective stress tensor; experimental damage investigation; high cyclic fatigue damage for uni-directional metal matrix composites; anisotropic cyclic damage-plasticity models for metal matrix composites. Part III Advanced topics in damage mechanics: damage in metal matrix composites using the generalized method of cells; the kinematics of damage for finite-strain elasto-plastic solids; a coupled anisotropic damage model for the inelastic response of composite materials. Appendix: listing of damage formulae.
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.
