Basic principles and examples of elasticity imaging aresummarized. The chapter focuses on static ultrasonicmethods, and it discusses the advantages and limitationsof this approach in the context of dynamic methods andalternative imaging modalities from the literature. We re-view the physics of continuum deformations as a way toevaluate various experimental approaches. A ...

introduction: agriculture as one of old sectors of economy has been important role in the supply food for peoples and raw materials. globalization causes rapid growth of world trade and reduces information and communications costs. globalization and rapid growth of trade increases the potential benefits of trade for agriculture from various aspects. the potential benefits of trade for agricultu...

A nonlinear small-strain elastic theory is constructed from a systematic expansion in Biot strains, truncated at quadratic order. The primary motivation the desire for clean separation between stretching and bending energies shells, which appears to arise only reduction of bulk energy this type. An approximation isotropic invariants, bypassing solution quartic equation or computation tensor squ...

Solid liquid crystals, formed by crosslinking polymeric nematics into elastomers are shown to display novel and complex elasticity. The internal (nematic) direction can experience a barrier to its rotation which couples to standard elasticity. We investigate this elasticity by considering imposed strains and demonstrate several new orientational phase transitions, caused by the interaction betw...
