Assessment of different methods for fatigue life prediction of steel in rotating bending and axial loading
Generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. The present paper investigates the effect of a notch on the fatigue life of the HSLA100 (high strength low alloy) steel which is widely applicable in the marine industry. Tensile test was conducted on specimens and mechanical properties were obtain...

متن کاملBending Fatigue Failures in Valve Steel
In the present paper the effect of defects (viz. pits, gouges and oxide inclusions) will be reported. Although certain defects were uniformly distributed over the specimen surface, the majority of all fractures started in the edge region. An explanation to this behaviour is presented in terms of stress enhancement in the edge regions due to edge deflections.
متن کاملFatigue Behavior of Heat Treated 30MSV 6 Vanadium Micro alloyed Steel
Fatigue behavior of a vanadium microalloy steel has been studied in this research. Here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. The results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. Optimal heat treatment cycle of the microalloyed s...
متن کاملSensitivity Analysis of Fatigue Behaviour of Steel Structure under In-Plane Bending∗
Abstract. The aim of the present paper is to analyse the influence of some input quantities on the fatigue resistance of a steel structure. The steel element subjected to many times repeated in-plane bending moment was analysed. The fatigue resistance was defined as the number of cycles causing the initial crack size propagation up to the critical size. The variability influence of input random...
