Voids in Materials

Voids in Materials treats voids of different shapes and forms in various materials, and examines their effects on material properties. The book covers the origins of voids in materials, how they are sometimes introduced in the form of hollow spheres, and the resultant properties of materials containing voids.There are many books that focus on foams (which intentionally incorporate voids into materials) and that cover voids incidental to or unwanted in the fabrication of non-porous materials. In fact, all materials have voids. This book starts from the premise that voids are pervasive in all material on some level. It goes beyond foams to provide a comprehensive overview of voids, a central reference for scientists and engineers to use for the effect of voids in materials.
- Includes 3D renderings of void geometries
- Explains how and why voids are introduced into materials across the length scales; from nanometer-scale voids up to macro-scale voids
- Provides a continuous picture of how material properties change as the volume fraction of voids increases, and the implications for product design

Gary Gladysz is an adjunct associate professor of materialsscience and engineering at the University of Alabama atBirmingham, United States and founder at X-Link 3D. Hereceived his PhD from the New Mexico Institute of Miningand Technology, where he participated in the NATOCollaborative Program with the German Aerospace Institute(DLR). Since receiving his PhD, he has led research efforts inuniversity, government, and industrial settings. He has extensiveresearch experience designing and characterizing thermosetcomposite materials for 3D printing, fibrous composites, ceramic composites,polymers, composite foams, and thin films. As a technical staff member at LosAlamos National Laboratory (LANL), he was technical lead for rigid composites andthermoset materials. In 2005 he was awarded the LANL Distinguished PerformanceGroup Award for his work leading materials development on the ReliableReplacement Warhead Feasibility Project. Additionally, while the US Army, he developedcomposite materials and test protocols for ballistic head protection. He hasserved on funding review boards for LANL, National Science Foundation, ACS, andthe Lindbergh Foundation. He has been guest editor on many issues of leadingmaterials science journals, including Journal of Materials Science and MaterialsScience & Engineering. He has organized many international conferences/symposiaon syntactic foams, composite materials, and innovative materials for additivemanufacturing. He started and chairs the ECI international conference series onSyntactic and Composites Foams. He currently lives in Boston, Massachusetts,United States.Professor Krishan Chawla obtained his BS from Banaras Hindu University and his MS and PhD degrees from theUniversity of Illinois at Urbana-Champaign, United States. Hehas taught and/or done research at (in alphabetical order)Arizona State University, Tempe, AZ (United States); EcolePolytechnique Federale de Lausanne (Switzerland); FederalInstitute for Materials Research and Testing (BAM), Berlin(Germany); German Aerospace Research Institute (DLR),Cologne (Germany); Instituto Militar de Engenharia (Brazil);Laval University (Canada); Los Alamos National Lab (UnitedStates); New Mexico Tech (United States); Northwestern University (United States);University of Alabama at Birmingham (United States); and University of Illinois atUrbana-Champaign (United States).He has published extensively in the areas of processing, microstructure, andmechanical behavior of materials, in general, and composite materials and fibers, inparticular. Besides being a member of various professional societies, he is Editor ofInternational Materials Review (published jointly by ASM International, UnitedStates and the Institute of Materials, London) and a member of the Editorial Boardof various journals. During 1989-1990, he served as a Program Director for metalsand ceramics in the Division of Materials Research, National Science Foundation,Washington, DC, United States. He serves as a consultant to the industry, USnational laboratories, and various US federal government agencies. In 1992 he wasthe recipient of the Eshbach Society Distinguished Visiting Scholar Award fromNorthwestern University. During the period of June, 1994 through June, 1995 heheld the US Dept. of Energy Faculty Fellowship at Oak Ridge National Lab. In 1996he was given the Distinguished Researcher Award by the New Mexico Tech. In 1997he was made a Fellow of ASM international. In 2000 he was awarded theDistinguished Alumnus award by Banaras Hindu University. He received thePresident's Award for Excellence in Teaching, University of Alabama at Birminghamin 2006. In 2018 he was awarded the Albert Nelson Marquis Lifetime AchievementAward.
