Publisher Summary This chapter analyzes bending of curved tubes. In 1910, A. Bantlin found, experimentally, that a curved tube is much more flexible in bending than a straight tube of the same cross section. The following year Von Karman gave a theoretical explanation of this phenomenon.

On Finite Bending of Pressurized Tubes
Journal of Applied Mechanics, 1959Abstract A unified treatment is presented of two well-known problems which have until now been considered separately. The two problems are: (a) the linear problem of pure bending of curved tubes, and (b) the nonlinear problem of pure bending of straight tubes. In both problems the effect of uniform internal pressure is included.

Bending collapse of folded tubes
International Journal of Mechanical Sciences, 2016Abstract Static and dynamic loading of a type of folded tubes under three-point bending are investigated in this work. The folded tubes are easily prepared, cost-effective and flexible in sectional shape, and hence quite promising to be applied widely in various engineering fields.

Optical measurement of tube bending
Precision Engineering, 1982Abstract Tube boring is usually accompanied by checking the degree of bending. Optically, this is done by experienced operators using their visual acuity and ability to ascertain the distortions of circular images. This classical method, while fairly accurate, has poor resolution and requires a long period of training.

Compensating for miter bends in cylindrical tubing
The Journal of the Acoustical Society of America, 2007Miter bends in cylindrical tubing perturb wave propagation in a way that may alter the desired resonance properties in musical instruments. The nature of the perturbations and several methods of compensating for them at low frequencies are described.

Wrinkling Limit in Tube Bending
Manufacturing Engineering, 2000Abstract Thin-walled tube bending has found many of its applications in the automobile and aerospace industries. This paper presents an energy approach to provide the minimum bending radius, which does not yield wrinkling in the bending process, as a function of tube and tooling geometry and material properties.

On bending stiffness of composite tubes
Composite Structures, 2011Abstract Theoretical formulations are provided for the determination of stiffness of composite tubes. A three-dimensional laminate theory is used to determine the equivalent flexural stiffness 〈EI〉 for composite tubes. The same theory is also used to determine the load versus axial strain of the tubes.

Bending of lightweight circular tubes
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2017The concept design (sizing) of thin-walled tubes subject to bending is dealt by resorting to rigorous design principles pertaining to engineering science. Multi-objective optimization is the proper theory that has been exploited. Minimum mass and maximum stiffness (minimum compliance) are the optimization objectives.

On Bending of Curved Circular Tubes
Journal of Engineering for Industry, 1970Based on the improved general solution for a thin, circular tube subjected to in-plane end moments, the effect of the radius ratio on the stress distribution, rigidity, and stress intensification factors is studied. The existing asymptotic solutions are reexamined and modified to reflect the effect of the radius ratio.
