摘要：

The present study relates to investigate the crack propagation behavior of 6063 T6 Al Aluminum Alloy under fatigue loading. The experimental as well as analytical analysis was done and for crack growth rate for 6063-T6 Aluminum Alloy. All analysis was done on Side edge notch specimen. A program was developed on Matlab (R) to calculate crack growth rate and effective stress intensity range ratio based on polynomial algorithm. That gave a very good agreement between them. The effective stress intensity range ratio (U) was found to depend on stress ratio (R). Variation in load range affects the crack growth rate. For constant load range its variation was negligible, constant C was almost constant at variable load range. Variation of maximum load affects constant C.
