Development in ongoing to allow Ple4Win to perform low-cycle fatigue (LCF) checks as well. In basis, these are similar to alternating yield calculations that the program is already capable of. LCF checks are a material-linear calculation giving insight into whether a pipeline might be damaged because deformations repeatedly introduce small material-plastic deformations. These deformations are infrequent and limited in number, it is not a vibration analysis. If correctly analysed, with the correct load cases and check criterions, LCF in pipelines can be managed and service range and or service life of a pipeline can be greatly increased.
