The paper presents the experimental results concerning fatigue crack growth in the cruciform plate specimens made of 18G2A (S355J0) steel. Two types of specimens were used, first with stress concentrator in form of central hole of 3.0 mm (with the minimum 1.86 mm wall thickness) in diameter and the second variant specimens without a hole (the minimum 1.25 mm wall thickness). The analytic and ...

Problems of evaluation of the life of rod elements of structures in axial cyclic loading are considered. The solutions are constructed within the limits of the phenomenological approach with use of the principles of the mechanics of a continuous surface. The fatigue life of rods in an asymmetric cycle and of rods with a stress raiser is considered and predicted. The calculation is made based ...

The current work investigates early material changes that manifest in aluminum alloy 7075 subjected to fatigue loading. Tension-tension specimens linearly tapered in width were exposed to cyclic loading with compliance and eddy current measurements made in-situ, while nano-indentation, surface potential, x-ray diffraction, and ultrasonic response were made ex-situ. Early stage damage ...
In welded structures, fatigue failures typically occur at the welded joints. Stress concentrations and small flaws in the welds are key parameters in determining the fatigue life of weldments. Traditionally, fatigue analysis of welded joints has been performed by attempting to determine the peak stress at the welded joint and then entering an appro...
