The free bending forming (FBF) technology is a new die-less forming process suitable for
bending complex-shaped thin-walled tubes with several bending radii. A new theoretical …

Free-bending is a novel bending technology suitable for tube and profile bending. It can
achieve accurate bending of tubes or profiles with different bending radii without die. In …

Simulation of thin-walled tube bending process not only results in a large amount of
calculation due to its high nonlinearity, but also leads to its non-uniqueness in simulation …

The rotary draw bending is one of the advanced thin-walled tube forming processes with
high efficiency, low consumption and good flexibility in several industries such as …

Tubes or pipe bends, sometimes referred to as “elbows” are key components of mechanical
systems with applications in many high technological industries such as aviation …
