FKM evaluation points

The FKM Guideline ("Rechnerischer Festigkeitsnachweis für Maschinenbauteile“ des Forschungskuratorium Maschinenbau) offers both a calculation method with nominal stresses at common notch locations (similar to DIN 743) as well as a calculation method with local stresses for components of any shape. The FKM evaluation point component (fkm_evaluation_point) was created for the associated parameters.

FKM evaluation points can be used as follows:

  • The FKM evaluation point can be connected with a Notches via an assembly relation. In this case, it uses the coordinate system of the associated shaft.

  • The FKM evaluation point can be connected with a notch calculation position of a shaft-hub connection via an assembly relation. In this case, it uses the coordinate system of the associated (inner) shaft.

  • The FKM evaluation point can be assigned to Assembly groups | assembly_group via assembly relations. In this case, it uses the coordinate system of the assembly.
