Nonstationary (NS) processes or NS dynamical systems (DS) are characterized by the appearance of the process (p) on the Control Parameters (CP) in the governing operators. That is, CP(NS) or Cp(p) where p is arbitrary processes: deterministic or rand

The main resonance of a laminated angle-ply column subjected to nonstationary parametric excitations is studied using the asymptotic method. The nonstationary processes used are either linear or cyclic excitation frequency, i.e. Ω(t) = Ω0 + βt or

Governing non-linear spatial-temporal partial differential equations are derived for rectangular orthotropic plates, taking into account transverse shear deformation—a significant factor in non-metallic structures. The resulting set of dynamic temp

This paper presents a numerical study for the bifurcations of a softening Duffing oscillator subjected to stationary and nonstationary excitation. The nonstationary inputs used are linear functions of time. The bifurcations are the results of either

This paper deals with the effects of non-stationary regimes on stationary chaotic motions and non-linear attractors: (1) linear variations of the excitation frequency, v = v in0 + α v t , and the amplitude B = B 0 + α B t ; (2) cyclic variations of

This is the first attempt to determine the effects of a broad range of linear non-stationary regimes related to the frequencies of external excitation v(t) ranging from evolving to robust, on dynamic responses of self-excited systems, governed by the

The necessary and sufficient conditions which must be satisfied by a physical process (e.g., the diffusion of heat through a body) in order that its mechanical effects can be represented by mechanical dislocations are derived for anisotropic media. I

A simply supported rectangular plate is subjected to a distributed periodic in-plane load of the form P = P 0 + d φ ( t ), where φ( t ) is a periodic function of time t with period T . Using a large deflection theory in-plane and lateral (parametri
