The single-crystal elastic moduli of San Carlos olivine, (Mg0.9Fe0.1)2SiO4, were determined at seven pressures between 2.5 and 32.5 GPa by Brillouin spectroscopy in a diamond anvil cell. The unit cell volume was also determined at each pressure (and ambient pressure) by single-crystal X-ray diffraction. The shear elastic moduli exhibit non-linear pressure dependencies. In particular, a non-line...

Periodic ocean tides continually provide a cyclic load on Earth's surface, the response to which can be exploited to provide new insights into Earth's interior structure. We used geodetic observations of surface displacements induced by ocean tidal loads to constrain a depth-dependent model for the crust and uppermost mantle that provides independent estimates of density and elastic moduli belo...

We derive an expression relating the axial load, the indentation depth, and the elastic constants of an orthotropic material, and simplify it to that for a cubic material (e.g., an FCC single crystal). We use this formula and results of three virtual (i.e., numerical) indentation tests on the same specimen oriented differently to find values of the elastic moduli, and show that they agree well ...

The modulus of elasticity Youngs modulus E is a material property, that. From the Hooks law the modulus of elasticity is defined as the ratio of the stress to.modulus of elasticity of the cultured SC cells examined in this study, in central, non-nuclear regions, ranged between. Johnson B.all require an effective E, the Youngs modulus or elastic modulus, to quantify. Elastic moduli, such as the ...

A micromechanical model was developed to predict the elastic moduli of hydroxyapatite (HA) whisker reinforced polymer biocomposites based upon the elastic properties of each phase and the reinforcement volume fraction, morphology, and preferred orientation. The effects of the HA whisker volume fraction, morphology, and orientation distribution were investigated by comparing model predictions wi...

Monte Carlo simulations of mono– and polydisperse two–dimensional crystals are reported. The particles in the studied system, interacting through hard–core repulsive Yukawa potential, form a solid phase of hexagonal lattice. The elastic properties of crystalline Yukawa systems are determined in the NpT ensemble with variable shape of the periodic box. Effects of the Debye screening length (κ), ...

Background Medial tibial stress syndrome (MTSS) is one of the most common causes of exercise-related leg pain in runners. Because stopping training due to pain from MTSS could decrease the athlete's competitiveness, it is necessary to construct MTSS prevention and treatment programs. However, the effect of running, which is believed to cause MTSS, on shear elastic modulus of the posterior lower...
