In this paper, the novel model of fluid-conveying imperfect pipe supported at both ends is established by considering the geometric imperfection and the geometric nonlinearity induced by mid-plane stretching. The integral-partial differential equation is discretized by the Galerkin method and solved by a fourth-order Runge–Kutta integration algorithm. Compared with the supercritical pitchfork bifurcation of the perfect pipe conveying fluid, the results show that the cusp bifurcation occurs in the imperfect pipe when increasing the flow velocity. Excellent agreement is observed between the numerical results and the analytical results. The two stable asymmetry bifurcation branches bring interesting phenomena in the post-buckling state. The global nonlinear dynamic behaviors of the imperfect pipe are studied by establishing the bifurcation diagrams. The influence of the geometric imperfection amplitude on the nonlinear response is leading to cusp bifurcation comparing with pitchfork bifurcation of the perfect pipe. When pulsation frequency is set as the bifurcation parameter, there are clear nonresonance ranges, low energy resonance ranges and high energy resonance ranges. In the high energy resonance ranges, the first mode vibration coexisting with the sub-harmonic resonance and combination resonance occurs. As the mean flow velocity and pulsation amplitude are set as bifurcation parameters, the vibration of the imperfect pipe becomes more and more complicated. The vibration exhibits far richer dynamic behaviors including periodic, multi-periodic, quasi-periodic, and chaotic motions. The viscoelastic damping can effectively suppress the vibration response and transfer the high energy resonance to the low energy resonance state. The improved model and corresponding results provide useful information for further studying the dynamic behaviors of fluid-conveying pipe with geometric imperfections.

Dilaton Black Hole

In this paper, we have studied particle collisions around a charged dilaton black hole in 2 + 1 dimensions. This black hole is a solution to the low energy string action in 2 + 1 dimensions. Time-like geodesics for charged particles are studied in detail. The center-of-mass energy for two charged particles colliding closer to the horizon is calculated and shown to be infinite if one of the particles has the critical charge.

The exciting opportunities promised by the unique properties of C60 can only be fully exploited if the growth and properties of this material can be understood. To this end we have carried out a study of the structural and vibrational properties of C60 adsorbed on the graphite(0001) surface. We observed a novel high-order periodicity at monolayer coverages which indicates that even the weak corrugation potential of the surface can perturb the geometry of the overlayer. Vibrational spectra show a low-energy resonance in the inelastic scattering cross section which we correlate with a resonance feature observed in the electron attachment cross section of C60. The lack of a measurable perturbation in the resonance upon going from multilayer to monolayer coverage indicates that a weak physisorption bond exists between the molecules and the surface.
