Abstract
For four structural materials – copper UNS C10300, aluminum 1050 UNS A91050, steel 1006 UNS G10060 and glass Corning 7900 (Vycor) – the dependence of the elastic wave velocity determination error on the sample and exciter size ratio of the composite vibrator was studied by modeling a compound vibrator in the COMSOL Multiphysics environment. The modeled materials were taken from those available in the COMSOL MULTIPHYSICS library. The obtained results were compared with the results for similar domestic materials: aluminum D16, steel 45, copper M3 and borosilicate laboratory glass TS. The minimum size ratios were established, at which the elastic wave velocity determination errors do not exceed the values required under the experimental conditions. An experimental verification of the modeling results by the compound vibrator method was carried out on samples made of copper M3.
