Ls. Cook et Rs. Lakes, VISCOELASTIC SPECTRA OF CD0.67MG0.33 IN TORSION AND BENDING, Metallurgical and materials transactions. A, Physical metallurgy andmaterials science, 26(8), 1995, pp. 2035-2039
In both torsion and bending, the alloy exhibited a viscoelastic relaxa
tion that could be modeled as a Debye peak superimposed on a power-law
low-frequency background. In torsion, the relaxed and unrelaxed shear
moduli were 9 and 12.2 GPa, respectively, maximum loss tangent was 0.
12. In bending, relaxed and unrelaxed Young's moduli were 15 and 35 GP
a, respectively; maximum loss tangent was 0.11. Behavior was linear to
at least 125 microstrain. These results are significant in that they
represent a unique combination of stiffness and loss in a monolithic m
aterial.
