RISE Fatigue Design Tool

Welcome to RISE Fatigue Design Tool


This site contains material for your fatigue design process.

  • Material and component tests can be ordered by contacting the RISE department for mechanical tests.

  • Test results can be uploaded an analyzed with respect to fatigue models including statistical aspects.

  • The results can be combined with your former knowledge to make safe designs.

  • The theory behind the tools can be studied in the given references.


Design Tool

To get access to the Design Tool you need a username and a password to be able to login to the site. To receive a username and a password you have to e-mail par.johannesson@ri.se with the following information, Name, Company, Phone and Email address. After that you will receive your username and password within a few days.

The calculation tool is free of use. It is run on a server maintained by RISE in Borås, Sweden and has thus a limited capacity in case of many simultaneous users.


This site is a research platform under continuous development. Please give us your comments by sending an email!

(150622) New server:

RISE Fatigue Design Tool has moved to a new server. In this process all uploaded user data had to be deleted. Please give us your feedback if anything is not working properly.

(131003) Rain flow tool updated:

The result from the rain flow filtering is now illustrated also by a range diagram and a level crossing diagram. The counted ranges can now also be downloaded.

(120613) A new book available from November 2013:


New feature: prior knowledge

The tools for the Wöhler curve and the spectrum Wöhler curve are supplemented with a possibility to include prior knowledge about the coefficient of variation of fatigue life

(111216) New course added
