The transient response of sandwich rings to concentrated radial impulsive loads is studied on the basis of a Timoshenko type theory. Solutions are obtained by integral transform techniques and also by representation in series of normal modes. Numerical results show that the ring's response is predominantly flexural and is highly dependent on the ratio of the extensional stiffness to the shear stiffness. It is also found that as the core stiffness decreases relative to the facing sheet stiffnesses, the influence of the thickness to radius ratio becomes more important.
