Goodman Diagrams to Print

Free and printable samples of Goodman diagrams are available in this post in high quality! Goodman diagram illustrates the Goodman relation, which in materials science and fatigue, it is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material. The diagram is sometimes called a Haigh diagram or a Haigh-Soderberg diagram, is a graph of (linear) mean stress vs. (linear) alternating stress, showing when the material fails at some given number of cycles. Take a look at the first sample diagram below.

A scatterplot of experimental data shown on such a plot can often be approximated by a parabola known as the Gerber line, which can in turn be (conservatively) approximated by a straight line called the Goodman line. Tension mean stresses reduce the fatigue life from that observed with completely reversed loading. The Goodman diagram, originally proposed in 1890, is a graphical representation of this effect. Other examples of fatigue life plot in Goodman relation can be seen in the following diagrams.

The alternating stress is plotted on one axis and the mean stress on the other. The allowable alternating stress with no mean stress is the fatigue limit. The maximum mean stress, with zero alternating stress, is the ultimate strength. A straight line is then drawn between the two points. Any combination of mean and alternating stress on this line will have the same fatigue life.
