heal.abstract	The aim of this experimental work is to explain the difference between the elastic moduli determined by the non-destructive method of ultrasound and the corresponding destructive methods. The former are known as dynamic elastic moduli and the latter as static elastic moduli. The dynamic elastic moduli of a material can be determined, using the NDT method of ultrasound, from a knowledge of the material's sound velocities and density. These moduli depend on the frequency of the ultrasound as well as on the viscoelastic behaviour of the material and they are completely different from the static moduli determined by the destructive methods. One well-established ultrasonic technique for making the velocity measurements is the pulsed-wave transit-time technique. It is a versatile and potentially very accurate technique that can also assess the material's elastic homogeneity and anisotropy.	en
