Fluid Structure Interaction VII
This paper is concerned with Euler buckling of long slender tubes subjected to internal pressure. A small disturbance from its perfectly straight form is imposed to the tube to account for the effect of the non-conservative, follower forces generated by fluid pressure. An equivalent lateral distributed force is derived by considering the geometric changes arising from the flexural deformation of the tube. A new differential equation governing the buckling mode of the tube considered as a columndoi:10.2495/fsi130121 fatcat:4w4inxzgyvc6tdyepidu75tzje
