Extension of Lighthill’s slender-body theory to moderate aspect ratios [PDF]
Journal of Fluids and Structures, 2018 Calculating the fluid forces acting on a moving body at high Reynolds number is crucial in many fluid-structure interaction problems, such as fish swimming or flutter instabilities. To estimate these forces, Lighthill developed the slender-body theory, which assumes a potential flow and an asymptotically small aspect ratio.

Stability analysis of large slenderness ratio horizontal hydraulic cylinder [PDF]
IOP Conference Series: Materials Science and Engineering, 2017 An improved two sections pressure bar method (ITSPBM) was presented to analyze the stability of the large slenderness ratio horizontal hydraulic cylinder. The friction moments, the bearing reactions at the two hinge joints as well as the clearances between the piston and the inner wall of the cylinder were taken into consideration.
