    This is a comprehensive guide to dielectric elastomer composites (DECs), which play an integral role in new electromechanically active smart-material technologies.

     Introducing the basic concepts behind DECs, the book is accessible to readers at all levels. It demonstrates how to implement practical problem-solving methods through nonlinear continuum mechanics and also discusses fibre-reinforced anisotropic DE composites and the electromechanically coupled behaviour of anisotropic fibre-reinforced DEs. Using practical examples throughout, it proposes models which utilise the strain energy function, nonlinear electro-elasticity, and nonlinear continuum mechanics. It presents clear guidelines for creating practical nonlinear finite element code, and introduces the reader to hyperelasticity.

     The book will be an accessible reference guide for students, researchers and engineers in the field of mechanical engineering, bioengineering, materials science, aeronautics, and robotics.
