Abstract

Similarities and differences between elasticity and viscoelasticity and between aeroelasticity and aero-viscoelasticity are critically examined and evaluated. Topics include constitutive relations, Poisson's ratio, energy dissipation, temperature effects on material properties, ther- mal expansions, loading histories, failure criteria, lifetimes, 1-D and Timoshenko beams, torsion, columns, plates, wave propagation, torsional divergence, control reversal, aerodynamic derivatives, utter and experimental determinations of viscoelastic properties. The full, partial or no possible applications of the elastic / viscoelastic correspondence principle are analyzed and discussed.
