Elastic and Mechanical Properties of Glass Specimen by Ultrasonic Method

Ultrasonic velocity and density measurements in Na2CO3 – ZnO – B2O3 and Na2CO3 – PbO – B2O3 composition glasses have been made at a temperature of 303K. These measured values are used to evaluate elastic modulii such as longitudinal, Young’s, bulk and shear, Poisson’s ratio, acoustic impedance, micro hardness, Debye temperature and thermal expansion coefficient. The results of these parameters have been discussed in terms of the structural and physical properties of the prepared glasses
