The text identifies and elaborates the fundamental principles of ferroelectricity, elastic phase transformation, and energy transfer mechanisms that form the common basis for understanding the functionality, application potential, and limitations of a smart materials system. While these principles are independent of specific kinds of materials or particular applications, they are explained in the context of a representative material and application. That is, the principles apply to whole groups of materials and can be used to differentiate between them. The present book endeavors to cover the basic physics pertaining to multifunctional materials: from mechanics, electrodynamics, thermodynamics, and condensed matter physics, either as a short summary or as applied to selected examples from the large group of multifunctional materials. Familiar physics principles are thus used as a guide to the nature and design of these materials. The book concentrates on three different types of multifunctional materials: piezoceramics, shape-memory alloys, and switchable fluids (electrorheological and magnetorheological fluids). These materials are the best-known commercially available multifunctional materials with the most applications. More interesting in the context of this book is the fact that although the aforementioned examples are all made from very different materials, namely, ceramics, metals, and fluids, respectively, their multifunctionality is based on the same underlying principle — a structural phase transition induced by an external field, either an electrical, magnetic, or thermal field. This is one reason why multifunctional polymeric materials are not discussed. In most cases, polymer multifunctionality relies on mechanisms besides phase transition.» weiterlesen» einklappen
