Wöhlergörbékkel

Wöhlergörbékkel, also known as Wöhler curves or S-N curves, are graphical representations used in materials science and engineering to illustrate the relationship between the stress amplitude (S) and the number of cycles to failure (N) for a given material under cyclic loading. These curves are named after the German engineer August Wöhler, who first developed the concept in the mid-19th century. Wöhlergörbékkel are typically plotted on a logarithmic scale, with the stress amplitude on the vertical axis and the number of cycles on the horizontal axis. The curve typically shows a decreasing trend, indicating that as the number of cycles increases, the stress amplitude that the material can withstand decreases. The point at which the curve intersects the horizontal axis represents the fatigue limit, or endurance limit, of the material, beyond which the material will not fail regardless of the number of cycles. Wöhlergörbékkel are used to predict the fatigue life of components and structures, and to optimize their design and maintenance. They are also used to compare the fatigue properties of different materials and to evaluate the effectiveness of fatigue mitigation techniques.
