Modulus of elasticity is one of the important
parameters of construction materials, which considerably influence
their deformation properties and which can also be determined by
means of nondestructive test methods like ultrasonic pulse method.
However, measurement results of ultrasonic pulse methods are
influenced by various factors, one of which is the natural frequency
of the transducers. The paper states knowledge about influence of
natural frequency of the transducers (54; 82 and 150kHz) on
ultrasonic pulse velocity and dynamic modulus of elasticity (Young&39;s
Dynamic modulus of elasticity). Differences between ultrasonic pulse
velocity and dynamic modulus of elasticity were found with the same
smallest dimension of test specimen in the direction of sounding and
density their value decreases as the natural frequency of transducers
grew.
