Building on the extraordinary success of eight best-selling editions, Callister's new Ninth Edition of Materials Science and Engineering continues to promote student understanding of the three primary types of materials (metals, ceramics, and polymers) and composites, as well as the relationships that exist between the structural elements of materials and their properties. This edition is again supported by WileyPLUS, an integrated online learning environment, (when ordered as a package by an instructor). Also available is a redesigned version of Virtual Materials Science and Engineering (VMSE). This resource contains interactive simulations and animations that enhance the learning of key concepts in materials science and engineering (e.g., crystal structures, crystallographic planes/directions, dislocations) and, in addition, a comprehensive materials property database.
