Piezoelctric and Elastic Constants of Bone

Martensitic Transformation and Elastic Constants

Elastic constants of natural quartz.

The elastic constants of a natural-quartz sphere using resonance-ultrasound spectroscopy (RUS) are measured. The measurements of the near-traction-free vibrational frequencies of the sphere are matched with the predicted frequencies from the dynamic theory of elasticity, with optimized estimates for the elastic constants driving the differences between these sets of frequencies to a minimal val...

Molecular Dynamics Investigation of The Elastic Constants and Moduli of Single Walled Carbon Nanotubes

Determination of the mechanical properties of carbon nanotubes is an essential step in their applications from macroscopic composites to nano-electro-mechanical systems. In this paper we report the results of a series of molecular dynamics simulations carried out to predict the elastic constants, i.e. the elements of the stiffness tensor, and the elastic moduli, namely the Young’s and shear mod...

Second Order Elastic Constants, Third Order Elastic Constants, Pressure Derivatives of Second Order Elastic Constants and the Low Temperature Thermal Expansion of D-tin

The complex behaviour of metals under severe thermal and stress environments is influenced markedly by their elastic properties. Indeed the response of a material tc~ an applied stress is always determined by the elastic constants and their pressure derivatives. Furthermore, both the mechanical and thermodynamic equation;$ of state of a metal that contains dislocations require detailed knowledg...

Pressure Derivatives of Elastic Constants of Single

present success was attained by making various technical developments, such as a liquid-solid hybrid system and indium bond between sample and buffer-rod. Analytical procedures were also developed both in required corrections for apparent travel times, and in formulation of pressure effect on elasticity. A distinct shear softening was found in MgAl2O4, and was predicted to occur in MgO beyond 3...
