the estimated points are located within the designated error interval. Subsequently, from the validation view point, it can be pointed out that the elasto-plastic model was in a position to adequately predict the number of cycles to failure. Moreover, Fig. 9 offers evidence that the devised technique is capable of successfully estimate fatigue lifetime. To sum up, the experimental results are close to the estimated values that are generated using the devised methodology and gave a similar pattern. This demonstrates applicability of the devised approach.
