It has become evident through the author's research that dynamic load factors are much influenced by solid viscosities for the case of a beam and rod subjected to transverse or longitudinal impulsive loads. This paper, treats the case of the ring subjected to uniformly distributed impulsive loads along the inner and outer edges. Loads are assumed to be damped exponentially. Three-element model is used and solid viscosities are represented by two parameters K and η. Approximate calculations are carried out on the assumption that Poisson's ratio is independent of time. The effects of solid viscosities on dynamic load factors of direct stresses in the circumferential direction at the inner edge are investigated. The analysis implies that, as the values of solid viscosities increase, dynamic load factors decrease remarkably in comparison with those for the case of a beam and rod.
