Calculating the energy transmission factor for a couplant layer with nonuniform thickness

详细

The energy transmission factor of a layer of couplant with nonuniform thickness has been calculated for a PET arbitrarily placed with respect to an arbitrarily shaped curved entry surface. The calculation results have been approximated for toroidal, spherical, and cylindrical surfaces. It is shown that in most cases of testing small-diameter articles, partial loss of acoustical contact can be disregarded when calculating the energy transmission factor.
