A comparison is made of the ductility limits of one mild (normal) and two high-tensile strength shipbuilding steels with an emphasis on stress state and loading path dependency. To describe the ductile fracture behavior of the considered steels accurately, an alternative form of ductile fracture prediction model is presented and calibrated. The present fracture model combines the normalized Cockcroft–Latham and maximum shear stress criterion, and is dependent on both stress triaxiality and Lode angle parameter. The calibrations indicate that, depending on the hardening characteristics of the steels, ductile fracture behavior differs considerably with stress state. It is demonstrated that the adopted fracture model is able to predict the ductile fracture initiation in various test specimens with good accuracy and is flexible in addressing the observed differences in the ductile fracture behavior of the considered steel grades.

Abstract Lucefin Group C30, C30E, and C30R are medium-carbon, non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. C30E and C30R may also be flame or induction hardened. C30, C30E, and C30R are widely used for small, moderately stressed parts, where higher strength levels are needed than can be achieved in the lower carbon grades, and also where toughness is more important than high tensile strength. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: CS-206. Producer or source: Lucefin S.p.A.
