Surface Crack Analysis Under Cyclic Loads Using Probabilistic S-Version Finite Element Model

The failure in engineering structures has always become a norm for the engineers to encounter. Thus, it is very important to improve the quantification of uncertainty in fatigue analysis. The main objective of this paper is to examine the effect to the uncertainties parameter in numerical calculatio...
