Abstract
Laboratory experiments were performed on four European mild carbon steel grades i.e. S275, S355, S460 and S690 to investigate their stress-strain and low cycle fatigue behavior under cyclic loading. The coupons were tested at room temperature and at 0.2%/sec constant strain rate for three different loading protocols: Monotonic tensile, variable strain amplitude, and constant strain amplitude of 1%, 3%, 5% and 7%. Charpy V-notch impact tests were also performed at 20°C and -20°C to determine the amount of energy absorbed by each steel grade at fracture. Aimed at validating the experimental results, numerical analysis was also performed using Finite Element Software ABAQUS.
