This book is devoted to the development of the local gradient theory of dielectrics. It presents a brief description of the known approaches to the construction of generalized (integral- and gradient-type) continuous theories of dielectrics. It describes a new continuum–thermodynamic approach to the construction of nonlinear high-order gradient theory of thermoelastic non-ferromagnetic polarized media. This approach is based on accounting for non-diffusive and non-convective mass fluxes associated with the changes in the material microstructure. Within the linear approximation, the theory has been applied to study transition modes of the formation of near-surface inhomogeneity of coupled fields in solids, disjoining pressure in thin films, etc. The theory describes a number of observable phenomena (including the surface, size, flexoelectric, pyroelectric, and thermopolarization effects in centrosymmetric crystals, the Meads anomaly, the high frequency dispersion of elastic waves, etc.) that cannot be explained within the framework of the classical theory of dielectrics.

By inclusion of the polarization gradient in the stored energy function of elastic dielectrics, the classical theory of piezoelectricity is extended to accommodate an electro-mechanical interaction in centrosymmetric (including isotropic) materials and a surface energy of deformation and polarization.

This unique compendium is devoted to flexoelectricity — the response of polarization to a strain gradient. The effect is analogous to piezoelectricity which is the response of polarization to strain itself. In contrast to piezoelectricity, which appears only in non-centrosymmetric materials, flexoelectric effect is allowed by symmetry in any materials. It becomes appreciable in nano-scale systems, where large strain gradients arise. The book discusses different nano-scale manifestations of the effect ranging from repulsion of acoustic and optic branches of materials to flexoelectricity in domain walls. It mainly caters for scientists, engineers and students.

This textbook introduces theoretical piezoelectricity. The second edition updates a classical, seminal reference on a fundamental topic that is addressed in every materials science curriculum. It presents a concise treatment of the basic theoretical aspects of continuum modeling of electroelastic interactions in solids. The general nonlinear theory for large deformations and strong fields is established and specialized to the linear theory for small deformations and weak fields, i.e., the theory of piezoelectricity. Relatively simple and useful solutions of many static and dynamic problems of piezoelectricity that are useful in device applications are given. Emphasis is on the formulation of solutions to problems rather than advanced mathematical solution techniques. This book includes many examples to assist and enhance students’ understanding of piezoelectricity and piezoelastics.

Held in May 1992 in Italy, the 4th International Spring Seminar on Nuclear Physics focused on recent developments which enhanced our understanding of the role of the various degrees of freedom which come into play in the nucleus. Consisting of four sessions, the first three sessions dealt with both theoretical and experimental issues centering on quarks and meson degrees of freedom, single-particle degrees of freedom and collective degrees of freedom. The fourth session discussed several important contributions that nuclear structure physics has made to the other research fields.
