Abstract:
In this study, the dynamic behaviour of a fluid conveying pipe resting on a two-parameter elastic foundation was investigated under four different boundary conditions. In the analyses, the fluid conveying pipe was modelled as an Euler-Bernoulli beam, and the equation of motion that describes the dynamic behaviour of the beam was obtained.
