Strength assessment with RifestPlus
For technical design and mechanical engineering computation and within related ranges of the industry since 1994 the FKM guideline for the computational strength assessment exists. The FKM guideline was developed under the leadership of IMA Dresden on behalf the “Forschungskuratoriums Maschinenbau e.V.” (FKM).
The guideline based on TGL standard, the earlier guideline VDI 2226 and further sources and was further developed.
The FKM guideline
- Allows the analytical strength assessment for rod-shaped, shell-shaped and block-shaped components under consideration of all relevant influences,
- Describes the assessment of the static strength and fatigue strength, the latter according to an assessment of the fatigue limit, of the constant amplitude fatigue strength or of the variable amplitude fatigue strength according to the service stress conditions,
- Is applicable for components, produced with or without machining or by welding,
- Allows an assessment in considering nominal stresses as well as local elastic stresses derived from finite element or boundary element analysis, from theoretical mechanics solutions or from measurements.
The practical application of strength calculation goes by using the calculation system RifestPlus.
