This paper presents a method to simulate fracture patterns of interacting ductile and cleavage fracture and experimental validation using API X80 Charpy test data. For ductile fracture, the stress modified fracture strain damage model is used, whereas for cleavage fracture, the maximum principal stress criterion is proposed. By combining ductile and cleavage fracture models, a numerical method to simulate interacting ductile and cleavage fracture is proposed. The proposed numerical method is validated by comparing with experimental Charpy test data at ductile-brittle transition temperatures. Comparison of fracture surfaces and impact energies shows good agreements.
