The Elastic Moduli of Heterogeneous Materials
Journal of Applied Mechanics, Transactions ASME, 1962Bounds and expressions for the elastic moduli of two or many phase nonhomogeneous materials are obtained by an approximate method based on the variational theorems of the theory of elasticity and on a concentric-spheres model. Theoretical results are in good agreement with experimental results for a two-phase alloy.

Macroscopic elastic moduli governing the incremental deformation of pressurized lungs are calculated on the basis of a micromechanical study of an individual lung element (alveolus). The spongy lung tissue (parenchyma) is presumed to be in an initial state of isotropic tension, and the lung alveolus is idealized as a pin-jointed truss in the shape of a

Elastic moduli and visco-elastic relaxation
Journal of Dentistry, 1994The elastic moduli of dental biomaterials are discussed in relation to the various intrinsic and extrinsic factors that can influence the magnitude of these parameters and hence the extent of modulus-matching with oral tissues. The time-dependent visco-elastic response is shown to be an important feature of both natural and many synthetic biomaterials.

The adiabatic elastic moduli of single crystal diamond have been determined by means of ultrasonic waves in the frequency range 20-200 Mc/sec. ${c}_{12}$ is much lower and ${c}_{44}$ much higher than respective values reported in the literature. In units of ${10}^{12}$ dynes per ${\mathrm{cm}}^{2}$, the newly determined values are: ${c}_{11}=10.76 ...

Abstract In this chapter, the calculation of second-order elastic constants and quasiharmonic phonons from quantum-based interatomic potentials (QBIPs) is addressed for nontransition metals at the pair potential level and for transition metals at the level of two-, three- and four-ion potentials.

Polyelectrolyte gels in poor solvent: Elastic moduli
The European Physical Journal E, 2000We study theoretically using scaling arguments the behavior of polyelectrolyte gels in poor solvents. Following the classical picture of Katchalsky, our approach is based on single-chain elasticity but it accounts for the recently proposed pearl necklace structure of polyelectrolytes in poor solvents. The elasticity both of gels at swelling equilibrium

The surface elastic moduli are the two-dimensional analogs of the elastic moduli in three dimensions. Experimental methods are reviewed briefly, and it is shown that Fourt's "elasticity index" for an oscillating vane or needle is dimensionally incorrect, whereas the formula proposed by Trapeznikov for an oscillating disk or ring is correct and can be
