摘要

Low-carbon steel plates play a crucial role in various industries such as automotive, energy, or structures. The hot rolling process to produce the steel plate may lead to the occurrence of edge cracks which requires to remove the affected edges, reducing the productivity in the manufacturing process. This study uses a stress-based fracture model considering the strain rate and temperature to predict the edge crack initiation of Si-added low-carbon steel during hot rolling. A new hardening model considering the strain rate and the temperature is proposed to model the target material including the softening behavior. Verification has been conducted by comparing finite element analysis with experiments from the hot rolling simulator under the same conditions. Using the strain-based fracture model led to an incorrect prediction of the edge crack initiation.
