Abstract: An experimental study of the response of three-mass systems to step changes of the base velocity is described. Recordings that show the beating that can occur between the vibrations in two ...

Abstract: The response of three-mass systems to step changes of the base velocity is discussed. It is shown that beating, which may occur between the vibrations in two normal modes, can result in a ...

Abstract: A test program was conducted to investigate the inelastic response behavior of internally pressurized tubes subjected to dynamic bending and torsion loads. The basic experiment was a drop test ...

Abstract: A normal mode solution is developed for concentric cylinders coupled by fluid between them and subjected to foundation input motion. Both time-history and spectral inputs can be specified. Example ...

Abstract: An approximate model for the elastic-plastic analysis of a pipe element under combined loading is developed. The model is obtained by generalizing a limit load solution for combined pressure, ...
