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 کاملHot Spot Stress Determination for a Tubular T-Joint under Combined Axial and Bending Loading
Finite element analysis of a tubular T-joint subjected to various loading conditions including pure axial loading, pure in-plane bending (IPB) and different ratios of axial loading to in-plane bending loading has been carried out. This effort has been established to estimate magnitudes of the peak hot spot stresses (HSS) at the brace/chord intersection and to find the corresponding locations as...

متن کاملEffect of the Loading Spectrum and History Length on Fatigue Life Distribution under Random Loading
One major source of error commonly encountered in determining the fatigue life of a given element arises from the loads involved, which are usually of random nature. As a rule, resistance analyses, carried out by simulation or tests, are done by using a loading history accounting for the real loads involved that is repeated indefinitely until failure is encountered. The result is one of the man...
متن کاملOptimal plastic design of a bar under combined torsion, bending and shear
Optimal plastic design of a bar or beam under torsion with superposed bending and shear is obtained via the boundary perturbation method. Effects of bending and shear are expressed by a small parameter α. The results of optimization of solid bars and of hollow bars are shown.
