The new Release 2021 of the calculation program is available

The new KISSsoft Release 2021 contains numerous innovations – for example, the 7th edition of the FKM Guideline has been implemented.

The revised 7th edition of the FKM Guideline (2020) contains a number of innovations in the nominal stress concept for shaft calculations. The revision includes a protective layer factor for galvanized steels, a new material group “Austempered Ductile Iron (ADI)” and equations for a cross-section of the shaft with hub seat (aligned with DIN 743). All material properties have also been adapted. The FKM guideline is thus state of the art.
