چکیده مقاله
A sample structural base support with a weld toe crack is considered Three different types of loading are applied to the structure: a bending moment, a shear load and a compressive load Three dimensional finite element analyses are used to study the variations of the mode I and mode II stress intensity factors with the crack length Because of complexity in geometry and loading conditions, the crack undergoes mixed mode loading It is shown that the mode II stress intensity factor is not negligible compared with the mode I stress intensity factor The variations of stress intensity factors with the crack length differ significantly for different loading conditions
