Numerical simulation of crack growth in a welded joint with defects
Апстракт
Research presented in this paper involves the numerical simulation of crack growth in a welded joint made of common structural steel S235JR2, but with the presence of a number of different welding defects, which represents a scenario that is not covered by relevant standards, in this case EN ISO 5817. After analysing several defect combinations, which could occur in reality, the one with the least favourable combination of stress concentration and plastic strain was selected as the relevant model. A crack was then introduced in the location where the stresses, caused by tensile loading of the welded joint model, were above the yield stress. The numerical analysis performed in this case involved different combinations of load magnitudes and crack length, in order to determine at which point the initial crack will start propagating.
