Abstract

The determination of elastic moduli by ultrasonic wave technique relies on the relationships between the acoustic wave velocities in a material and the density and elastic properties of the material. Moreover ultrasonic wave propagations measurements afford a non-destructive means for determining elastic constants. This can be done by introducing longitudinal and transverse waves in the test objects and measuring corresponding velocities. Under this project, 2 and 5 MHz ultrasonic longitudinal and shear wave probes were used to measure the longitudinal and shear velocities of the supplied Aluminium alloy samples. Modulus of the samples was determined from the measured velocity using the software “ Ultrasoft” developed at NML. Measurements were carried on the supplied samples and report of each measurement was submitted within 10 days of receiving the samples.
