On the dynamics of propagating buckles in pipelines

A combined experimental and analytical study of the dynamic propagation of buckles initiated in long pipes under external pressure is presented. The experiments involve measurement of the steady-state velocity of buckles initiated in stainless steel tubes with D/t=27.9. Results from tubes pressurized by air or water are presented for pressure levels ranging from the propagation pressure to the collapse pressure of the tube. The buckle velocity...
