BasquinGleichung

The Basquin equation is a mathematical model used to predict the fatigue life of materials subjected to cyclic loading. It is named after the German engineer Ernst Basquin, who first proposed the relationship in 1910. The equation is expressed as:

S = a * N^b

where S is the stress amplitude, N is the number of cycles to failure, and a and b are material constants. The Basquin equation is a power-law relationship that describes the inverse relationship between stress amplitude and the number of cycles to failure. It is often used in conjunction with the Coffin-Manson equation to predict the fatigue life of materials under both high and low cycle fatigue conditions.

The Basquin equation is widely used in engineering and materials science to design and analyze components subjected to cyclic loading, such as those found in aerospace, automotive, and mechanical engineering applications. It provides a simple and effective way to predict the fatigue life of materials, taking into account the effects of stress amplitude and the number of cycles to failure. However, it is important to note that the Basquin equation is an empirical model and its accuracy depends on the specific material and loading conditions. Therefore, it is often used in conjunction with experimental data to improve its predictive capabilities.
