Lw. Anson et Rc. Chivers, ULTRASONIC VELOCITY IN SUSPENSIONS OF SOLIDS IN SOLIDS - A COMPARISONOF THEORY AND EXPERIMENT, Journal of physics. D, Applied physics, 26(10), 1993, pp. 1566-1575
Twelve theoretical models for the ultrasonic velocity in a system cons
isting of a solid matrix containing solid spherical inclusions have be
en compared with experimental data obtained from the literature. Four
of the models failed to predict the experimentally observed minimum in
the velocity-inclusion concentration curve, and can therefore only be
considered suitable for low-concentration computations. All of the re
maining models give qualitative agreement with the experimental system
s considered and no one model is obviously superior to the others. The
re is a clear need for more high quality experimental data on solid-so
lid suspensions.
