...Hidemi Akimoto; Katsuhiko Nagai; Naoki Sakurai In this paper, a nondestructive method to measure bulk and shear viscosities of a homogeneous viscoelastic sphere using free vibration is investigated by taking into account a single Voigt model for viscous and elastic stress tensors. For the viscosity...
