Abstract : The axial symmetric equations of motion for a cylinder wrapped with an orthotropic jacket are used to compute the effect of jacket properties on the lowest axial symmetric critical velocity. It is shown that an orthotropic jacket. often used to strengthen a cylinder, may actually result in a critical velocity lower than that of the cylinder without the jacket unless the jacket stiffness to mass properties are sufficiently high.
