Nonlinear Elasticity Background
2013In this chapter we summarize the main ingredients of continuum mechanics and their application to nonlinear elasticity with a view to the subsequent development of the nonlinear theories of electroelastic and magnetoelastic interactions. The setting is purely mechanical without reference to any electromagnetic effects.

In tissue the Young's modulus cannot be assumed constant as a function of preload. For example, direct mechanical measurements on human prostate show up to a threefold increase in Young's modulus over a 10% deformation. In conventional elasticity imaging these effects produce strain dependent elastic contrast.

Effective elastic constants in nonlinear elasticity
Journal of Applied Physics, 2005The Lagrangian elastic constants cIJ and cIJK which are given in data-books are not stress-strain relationships. The relationships between them and any experimental observables are far from straightforward to evaluate under conditions of finite deformation when elasticity is nonlinear.

Nonlinear interactions in elastic resonators
Ultrasonics, 2006This work is dedicated to nonlinear interactions in elastic resonators. It is supposed that a resonator wall yields locally to the inner pressure. The elastic wall of the resonator induces strong dispersion and dissipation of acoustic energy. The dispersion can significantly influence studied nonlinear interactions which are ineffective because the ...

We begin with a multi-layer composite material, composed of interacting components \({{\varOmega }^{(1)}}\) and \({{\varOmega }^{(2)}}\) (Fig. 8.1).

Nonlinear elasticity in nanostructured materials
Reports on Progress in Physics, 2011We elaborate on a blended continuum/atomistic theoretical picture of the nonlinear elastic properties of nanostructured materials, looking at diverse aspects such as dispersions of inhomogeneities within a matrix, random or graded nanograined materials, two-dimensional atomic sheets.

Most engineering structures are purposely built to be stiff so that typically the only source of nonlinear displacements is associated with the out-of-plane deflections in thin-walled flexible structures as discussed in Chap. 2. The situations of primary concern to us in structural statics (especially when analyzing light-weight structures) are when ...

Two states of the body are considered. One is called the initial state (this usually means the unstressed body state), while the other is the actual state, that is the stressed body state. Note that from a geometrical point of view this is a conditional definition; however, it becomes important when physical relations are considered.
