Linear flow splitting 

is a new massive forming process for the production of bifurcated profiles in integral style. The semi-finished part is a plane sheet metal which is transformed at ambient temperature by a specific tooling system, consisting of obtuse-angled splitting rolls and supporting rolls. 

Distribution of equivalent plastic-strain (PEEQ) after several splitting steps: 21, 27, 33, 42. 

PEEQ parallel to the flange surface in a distances of X = 0.05, 0.25 and 1.5 mm below the top surface.

Material flows from the web to the flanges during the loading steps.
