Solid-state viscoelastic shear moduli (G0 and G00) of cylindrical polymer foams are measured as a function of frequency. Extruded samples are produced via a cylindrical die to obtain foams of various morphologies. To perform the shear measurements, a modification of the torsion rectangular setup on an ARES rheometer is made. The setup, calibration, and test conditions are presented. The data are discussed and compared to simple models taken from the literature.
