Fatigue Behavior - an overview ScienceDirect Topics

The fatigue behavior of machine components and devices generally depends on the intrinsic properties of the materials resistance, that is, the fatigue limit, and above all on a correct design of the object. In particular, among the main factors that can influence the fatigue behavior of a material, the following ones are the most important: Fatigue Properties Estimation and Life Prediction for In this study, several estimation methods of fatigue properties based on different monotonic mechanical parameters were first discussed. The advantages and disadvantages of the Hardness Method proposed by Roessle and Fatemi were investigated and improved through the analysis of a total of 92 fatigue test data. A new Segment Fitting Method from Brinell hardness was then proposed for the fatigue Fatigue strength of filletwelded joints at subzero In the present study, welded normal and high strength steel joints are tested to analyse the fatigue strength under subzero temperatures.
