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.

Gary Gladysz is an adjunct associate professor of materials science and engineering at the University of Alabama at Birmingham, United States and founder at X-Link 3D. He received his PhD from the New Mexico Institute of Mining and Technology, where he participated in the NATO Collaborative Program with the German Aerospace Institute (DLR). Since receiving his PhD, he has led research efforts in university, government, and industrial settings. He has extensive research experience designing and characterizing thermoset composite materials for 3D printing, fibrous composites, ceramic composites, polymers, composite foams, and thin films. As a technical staff member at Los Alamos National Laboratory (LANL), he was technical lead for rigid composites and thermoset materials. In 2005 he was awarded the LANL Distinguished Performance Group Award for his work leading materials development on the Reliable Replacement Warhead Feasibility Project. Additionally, while the US Army, he developed composite materials and test protocols for ballistic head protection. He has served on funding review boards for LANL, National Science Foundation, ACS, and the Lindbergh Foundation. He has been guest editor on many issues of leading materials science journals, including Journal of Materials Science and Materials Science & Engineering. He has organized many international conferences/symposia on syntactic foams, composite materials, and innovative materials for additive manufacturing. He started and chairs the ECI international conference series on Syntactic and Composites Foams. He currently lives in Boston, Massachusetts, United States.
