Search Approach

Based on the Floquet-Liapunov theory, this paper proposes an efficient one-dimensional search approach for stability analysis of pipes conveying pulsatile flow. The instability boundaries of a clamped-clamped pipe analyzed in this paper. The numerical results are satisfactory compared with existing results. Moreover, an instability region which failed to appear in ordinary numerical analyses is detected by our computations.

A method is presented for the numerical analysis of the aerodynamic characteristics of a two-dimensional single-surface porous sail. In this analysis the authors apply a series of Jacobi polynomials to express the pressure distribution and chordwise shape, considering carefully leading-edge conditions. It is found that the aero-dynamic stability of a sail increases with increasing porosity. The effects of porosity on the value of the life coefficient and the position of the centre of pressure are shown in diagrams as functions of angle of attack and of excess length of membrane over the chord length.

Energy Increment

In this paper the concept of energy increment map is presented for stability judgement of elastic truss structures under arbitrary dynamic excitations. The modified member theory is adopted to establish the equilibrium equations of the structures. The motion trajectories of structures are numerically solved in time domain and the corresponding stability states are studied according to the energy increment map. Numerical examples show that the method of this paper can lead to satisfactory results in dynamic stability analysis of elastic truss structures.
