Cyclic loading may result in material failure. This tool predicts the fatigue curve of our grades for any given temperature and humidity. Easily calculate after how many cycles your part will fail, or how much stress it is able to endure!
Fatigue is the failure of the material (tensile bar) due to cyclic loading. Various cyclic loadings can be applied, characterized by the ratio 'R' between the minimum and the maximum amplitude.
Phenomenological fatigue model with temperature (and humidity) dependent parameters. Model predicts fatigue lifetime (number of cycles-to-failure) under isothermal conditions (excluding effects of viscous heating).

Why can't I select all DSM grades?
We're in the process of expanding this tool to more grades, but this depends on the availability of experimental data as well as on the demand for that particular grade. Let us know what grades you're looking for by filling in the feedback form on the bottom right of the page!
