The ability to predict conditions that induce irreversible damage in hot-rolled material is vital for product quality. In the current work, parameters for Johnson-Cook strength and damage models were determined using high-temperature mechanical testing on medium-carbon vanadium-microalloyed steels. Finite element models were developed for two hot rolling bar schedules, considering both square to round and round to round continuous casting and hot rolling processes. The experimentally determined material models were implemented along with the industrial hot rolling parameters. Using simulation results, the locations of regions with a high probability of damage initiation were predicted.
