...Atef Mohany; Victor P. Janzen; Paul Feenstra; Shari King This paper describes a test program that was developed to measure the dynamic response of a bundle of steam generator U-tubes with anti-vibration bar (AVB) supports, subjected to Freon two-phase cross-flow. The tube bundle geometry is similar...

.... 11 . Furthermore, the density of the reduced cross-sectional bar was decreased by a half. Then, the energy dissipation increased due to the smaller structural density as shown in Fig. 12 . Again, the 3D wet model and the 1D equivalent model agreed well for the energy dissipation rate. On the other...

... a progressive damage at the supports through fretting wear or fatigue. Antivibration bar supports used to limit pipe vibrations are described. An assessment of analytical, numerical, and experimental techniques of fretting-wear problem of pipes in heat exchangers will be given. Other topics related to this part...

... distributions under the applied primary loads. By modifying the local elastic moduli it is possible to obtain inelastic-like stress redistribution. The method is demonstrated with a “two-bar structure” model based on analytical routine. The analysis is then applied to some typical shakedown problems including...

.... A procedure for calibrating the multiaxial damage constants from notched bar test data is described for multiaxial implementations. Also described is a study on the effect of uniaxial specimen orientation on anisotropic damage evolution. A Norton creep material constant B material...

...R. Adibi-Asl; R. Seshadri Limit loads are determined in this paper by invoking the concept of equivalence of “static indeterminacy” that relates a multidimensional component configuration (with cracks) to a “reference two-bar structure.” Simple scaling relationships are developed that enable rapid...
