Abstract: This thesis study and examines the behavior of high strength steels (HSS) during fatigue utilizing S-N curves of models based on the Palmgren-Miner Rule and some invented hypotheses, such as Haibach's model, Corten-Dolan's model and Serensen-Kogajev model. Firstly, a detailed mechanical testing will be done and discussed to ensure creating a proper understanding of the two types of steel that will be the focal point of the research. The curves created are interpolated using measured data form cyclically loaded of the steel to create the relation between the number of cycles the material can withstand before reaching failure state and the level of stress applied on a variety of specimens with different homogenizes but similar characteristics. The accuracy of each model is determined for each grade of steel, the S690 and the S960. Then we will conclude by the end of the work which can be considered suitable and which not of each model and an explanation of the reasoning behind the results achieved to ensure better outcome in future related work.
