Abstract Existing models of bulk modulus for aerated hydraulic fluids primarily focus on the effects pressure and air fraction, whereas effect temperature is disregarded. Based lumped parameter method full cavitation model, combined with improved Henry’s law polytropic course equation, a theoretical model dynamic an fluid derived. The system pressure, are investigated using controlled variable ...

A joint inversion method is developed to estimate the elastic constants of two elastic, homogeneous, isotropic media separated by a flat horizontal boundary. The method jointly uses P and S-converted wave reflection amplitude-versusangle (AVA) data and seeks the Poisson’s ratios of each layer, ratios of the densities and bulk modulus of the layers. The generalized linear inversion (GLI) method ...

Pulmonary emphysema is a connective tissue disease characterized by the progressive destruction of alveolar walls leading to airspace enlargement and decreased elastic recoil of the lung. However, the relationship between microscopic tissue structure and decline in stiffness of the lung is not well understood. In this study, we developed a 3D computational model of lung tissue in which a pre-st...

SUMMARY We derive exact expressions for the thermal expansivity, heat capacity and bulk modulus assemblages with arbitrarily large numbers of components phases, including influence phase transformations chemical exchange. illustrate results in simple two-component, two-phase systems, Mg–Fe olivine-wadsleyite Ca–Mg clinopyroxene-orthopyroxene a multicompontent model mantle composition form pyrol...

We show that composite materials can exhibit a viscoelastic modulus (Young's modulus) that is far greater than that of either constituent. The modulus, but not the strength, of the composite was observed to be substantially greater than that of diamond. These composites contain bariumtitanate inclusions, which undergo a volume-change phase transformation if they are not constrained. In the comp...
