Steel Fatigue Strength Predictor

Disclaimer: The results from this tool are estimates based on data consisting of a set of experimental measurements. All results are provided for informational purposes only, in furtherance of the developers' educational mission, to complement the knowledge of materials scientists and engineers, and assist them in their search for new materials with desired properties. The developers may not be held responsible for any decisions based on this tool.

Welcome to the steel fatigue strength predictor. This tool is built using experimental data of more than 400 steels, available from the Japan National Institute for Materials Science (NIMS) MatNavi database. This database consists of processing and composition information of steels, along with the experimentally measured rotating bending fatigue strength (10 million cycles). Various data analytics techniques such as feature selection and regression modeling were used to obtain highly accurate fatigue strength prediction models using a small non-redundant set of six composition parameters and three processing parameters.

The tool estimates the fatigue strength of the steel based on the composition and processing parameters entered by the user. To obtain the fatigue strength prediction, please enter the attribute values below, and click the submit button.
