Elastic and Mechanical Properties of Some Glass Specimen by Ultrasonic Method

Ultrasonic velocity, density and attenuation measurements in V₂O₅-P₂O₅, V₂O₅-ZnO-P₂O₅ and V₂O₅-MnO-P₂O₅ composition glasses have been made at the room temperature by making use of pulse echo method. These values are utilised to evaluate elastic moduli such as longitudinal, Young's, bulk and shear, Poisson's ratio, acoustic impedance, micro hardness, internal friction, Debye temperature and thermal expansion coefficient. The structural and physical properties of the glass samples have been discussed in the light of the above parameters.
