Finned projectiles that are meant to be unspun could acquire small roll rates in #ight due to slight con"gurational asymmetries. If the roll rate matches the natural yawing frequency of the projectile, a resonance phenomenon takes place resulting in yaw ampli"cation, and possible loss of stability.
We consider, numerically and analytically, a wave pulse passing a point where the dispersion coefficient changes its sign from focusing to defocusing. Simulations demonstrate that, in the focusing region, the pulse keeps a soliton-like shape until it is close to the zero-dispersion point, but then,
A method of analysis for the forced vibration of a beam with viscoelastic boundary supports is proposed based on complex normal mode analysis. The viscoelastic support regions are first described in terms of equivalent complex stiffness coefficients, and then using the complex modes of the beam syst
