Material characteristics

The mechanical parameters — modulus of elasticity, stretching limit, modulus of hardening, carbon content and alternating-forming parameters — that describe a process material and largely determine its forming behavior in elastic-plastic cold forming.

Mechanical material characteristics describe a process material and largely determine its forming behavior. The modulus of elasticity, elongation or stretching limit, modulus of hardening, carbon content and the parameters of alternating forming used to derive the Bauschinger effect are the most important characteristics in connection with elastic-plastic cold forming.
