FKM Guideline


The FKM guideline defines analytical stress assessments for general purpose engineering applications. It includes steel, stainless steel, cast iron, aluminum and cast aluminum. Base material and weld seams can be analysed with respect to static strength, constant amplitude and variable amplitude fatigue strength. FKM guidelines 6th and 7th edition are available in LIMIT®.

LIMIT® Implementation

LIMIT® includes all features of the FKM guideline, including local stresses, nominal and structural stress concepts and effective notch stress approaches. The results are available as degrees of utilization.

Fields of Application

  • general mechanical engineering
  • fun rides such as roller coaster vehicles
  • railway applications

Further Information
