Mechanics of functional materials Conventional books on the mechanics of materials treat elastic deformations of solids through one dimensional models for the extension of rods torsion of shafts and bending of beams. In functional materials mechanical thermal electric and magnetic fields interact among themselves and therefore need a more comprehensive model. This book presents a systematic treatment of the three dimensional theories for these coupled phenomena and the corresponding one dimensional models for extension torsion and bending. This book adopts a mixed approach by devoting the first half of the book to the development of the three dimensional theories of elastic thermal electric and magnetic fields as well as their interactions in dielectrics conductors and semiconductors. The remainder of the book presents the one dimensional models for extension torsion and bending systematically
