Baumann, C., Mates, S. P., Krall, S., & Bleicher, F. (2023). Introduction of a constitutive material model considering variable carbon content for cutting simulation. In V. Schulze & D.

Carbon steels show complex strain hardening and dynamic strain aging effects under high plastic strains, high strain rates, high temperatures and high heating rates, and thus a sufficiently complex constitutive model is needed to capture this behavior. Carbon content in such steels (e.g., AISI 1018, 1045, 1075) influences strength and hardening as well. A recently-developed material model for 1045 steels was therefore modified to capture the effect of carbon content on the material response. The model can also capture time-dependent plastic response associated with interrupted austenite transformation under short (sub-second) heating times, for the simulation of machining operations.
