Study of fatigue crack growth in 6063-T6 aluminum alloy

The present study relates to fracture mechanics and its aim is to validate the experimental analysis with analytical analysis and find out a relationship between loading parameters and crack growth rate for 6063-T6 Aluminum Alloy. All analysis was done on Side edge notch specimen. The constant U was found to depend on stress ratio R. Variation in load range affects the crack growth rate constant m. For constant load range its variation was negligible, constant C was almost constant at variable load range. Variation of maximum load affects constant C
