Abstract: Abstract Monopole towers are slender structures usually employed for telecommunication, for meteorological measurements or for massive lighting poles. The structure is made-up of a vertical cantilever column constrained to the ground by a massive foundation.… read more here.

DOI: 10.1016/j.jsv.2017.01.035
Abstract: Abstract A novel idea that applies the multiple scale analysis to a discretized decoupled system of gyroscopic continua is introduced and an axial moving string is treated as an example. First, the invariant manifold method… read more here.

DOI: 10.1142/s0219455418500220
Abstract: Dynamic stochastic stability of a two-degree-of-freedom gyroscopic system under bounded noise parametric excitation is studied in this paper through moment Lyapunov exponent and the largest Lyapunov exponent. A rotating shaft subject to stochastically fluctuating thrust… read more here.
