Assume you need to bend a 5 mm thick S235JR steel sheet with an internal radius of 5 mm (r/t = 1) to a 90° angle. The leg lengths (from the apex of the bend) are 50 mm and 100 mm.

The standard’s primary contribution is the —the compensation added to the sum of the leg lengths to account for material elongation or compression during bending. Din 6935 Standard Pdf

Preventing material failure or cracking by adhering to material-specific limits. Assume you need to bend a 5 mm
