Tube Bending Under Axial Force and Internal Pressure

Tube bending is a widely used manufacturing process in the aerospace, automotive, and various other industries. During tube bending, considerable in-plane distortion and thickness variation occurs. Additional loadings such as axial force and internal pressure can be used to achieve better shape control. Based on plasticity theories, analytical models are developed to predict cross-sectional ...

Ro = R + ( T / 2 ) Wall factor: Fw = T / W. "D" of bend: Fd = R / T. Bend difficulty rating (the higher the value, the more difficult the bend is to make; rule of thumb only): Where "Kr" = a constant for material rigidity (assign the same value to "Kr" as you would to calculate pressure die length; a value of 2 is suitable for most ...

Piping Elbows vs Bends for Piping and Plumbing Systems (PDF)

A PIPING BEND is simply a generic term in piping for an "offset" – a change in direction of the piping. It signifies that there is a "bend" i.e, a change in direction of the piping (usually for some specific reason) – but it lacks a specific, engineering definition as to direction and degree. Bends are usually made by using a ...

K-Factor for tube bending : r/engineering - reddit

FOr tube/pipe bending, a thinning factor is applied when taking into account the thinning that occurs on the outer circumference due to stretch of outer fibres. This adds extra margin to the thickness considered for tube before bend. So, for strength design the reduced thickness suffices. Design codes have various recommendations.
