Static strength

For static loading or loading with very low cycle numbers usually the assessment against static material failure or collapse is sufficient. If cyclic yielding can be excluded, then usually moderate load cycle numbers up to 10000 are no problem. LIMIT offers static strength assessments for base material and welds. The most refined procedure is part of the FKM module within LIMIT and takes into account the influence of multiaxial stress states on the ductility of the material.

Currently low cycle fatigue (see figure here) involving cyclic yielding is not covered by the codes and guidelines implemented in LIMIT.
