FLUID CONVEYING PIPE WITH SHEAR AND COMPRESSIBILITY

Stability of a compressed fluid conveying pipe is analyzed. It is assu med that the pipe is fixed at one end and free at the other. At the fr ee end the pipe is loaded with a concentrated force od constant intens ity and fixed direction. The constitutive equations for the pipe are t aken in a form that allows pipe axis extensibility and rakes into acco unt the influence of shear stresses. It is shown that the pipe could l ose stability either by divergence or by flutter. Both flutter and div ergence stability boundaries are determined for several values of para meters.
