| Abstract: | Sound
velocities and elastic moduli of some minerals viz MgO, MgAl2O4,
Al2O3, Y3Al2(AlO4)3
and pyrope (Mg3Al2Si3O12) up
to a pressure of 200 GPa have been studied. The pressure-density relationships
have been determind using the Hama-Suito theory of equation of state based on
the augmented plane wave (APW) and quantum statistical methods. The elastic
moduli such as bulk modulus, shear modulus, Young’s modulus and Poisson’s ratio
have been calculated as a function of pressure. The relationships between sound
velocities and elastic moduli have been used to obtain values of compressional
wave velocity and shear wave velocity. The results are found to present close
agreement with the available experimental data. Both compressional and shear velocities
are in good agreement with the available experimental data |
