By combining data from compressional and vibrational spectral studies, both the zero-pressure isothermal bulk modulus ( B T ,0 ) and its first pressure derivative ( B ′ T ,0 ) can be directly and independently calculated for a material without employing an empirical equation of state. On the...
The bulk modulus is also evaluated for MgO in the temperature range 300 - 200 K and down to a compression of V/V0 = 0.6 using an expression based on the Chopelas-Boehler approximation. The results obtained agree well with the ab-initio values determined by Isaak et al. 展开 ...
The change in the relative volume of the object when stress acts on the surface of the object uniformly is called Bulk modulus. The solved examples of Bulk modulus help in understanding the concepts well.
In this paper, we consider an acoustic equation with incomplete data, where the bulk modulus coefficient and initial conditions are partially known. Our goal is to get information about the bulk modulus coefficient independently of the initial conditions from boundary observations. To achieve this goal...
1 I was searching for an expression for the bulk modulusBBfor a gas that obeys the van der Waals equation ("van der Waals gas" from now on). Since for an ideal gas we have thatB=γPB=γP(whereγγis the adiabatic index andPPthe pressure), I thought that I could arrive to som...
Liquid alkali metals: Equation of state and reduced-pressure, bulk-modulus, sound-velocity, and specific-heat functions In this paper we extend our previous work on universality in solids to the study of liquid metals. As in the case of solids, to a good approximation, in th... H ...
A generalization of the Lindemann law given previously is used in conjunction with the Murnaghan equation of state for a solid to derive a law of reduced states for fusion, valid for the case of classical excitation of the lattice vibrations at melting. If the bulk modulus and volume of the...
definitions of the bulk modulus and the volume coefficient of thermal expansion. Both of these coefficients are pressure and temperature dependent; therefore, it is necessary knowing the derivatives of these parameters. These derivatives are also pressure and temperature dependent which makes the P-V-...
where co is the sound speed, defined by the isentropic bulk modulus of the fluid. Typical values are co = 343 m/s in air and co = 1500 m/s in water. It follows that the density perturbation for a sound level of 140 dB (re 20 μPa) in air is about 1.7 × 10− 3 kg/m3,...
