Bending and Forming of Tubing

2006
Abstract This article begins with a discussion on the factors considered in the selection of bending methods. It presents a detailed description of the types of bending method, machines and tools used in the bending and forming of tubing. The article provides an overview of bending tubing with and without a mandrel and hot bending.

Titanium Tube Bending for Aerospace

Aircraft Engineering and Aerospace Technology, 1989
TODAY'S modern aeroplanes require light weight components to satisfy the aeroplane's flight performance requirements. More than ever before new designs require commercially pure titanium (Grades A40, A55, and A70) because of the needs for high ductility associated with moderate strength, high corrosion resistance and good weld ability.

Bending of Curved Thin Tubes

Journal of Applied Mechanics, 1945
Abstract The stress distribution in curved tubes under the action of applied couples acting either in the plane of curvature of the tube or perpendicularly to that plane greatly differs from the conventional beam distribution, especially in the case of tubes with thin walls and a great curvature of the center line.

Tube bending on the roll machine

AIP Conference Proceedings, 2013
Computer simulation of the elastic-plastic tube bending by pushing on three-roll machine with work hardening effect consideration is presented. Non-steady tube bending process for specified curvature is simulated with axis of bending roll displacement, followed by transfer to the steady-state bending process.

Bending Instability of Composite Tubes

Journal of Aerospace Engineering, 1996
In this paper, a set of simple formulations is derived to predict the instability critical loads of orthotropic composite tubes under pure bending. The formulations are based on the assumption that the instability of an orthotropic composite tube under pure bending is due to the ovalization of its cross section.

Nonlinear Bending of Curved Tubes

1984
The determination of the nonlinear deformation and of the collapse load of elastic curved tubes subjected to bending loads is investigated. The precritical deformation of the tubes is determined on the basis of the semi-membrane theory. The stability analysis is done with the aid of the hypothesis of local buckling. The collapse loads are compared with
