A low cycle fatigue criterion based on non-linear fracture mechanics

Anders Lundström, Johan Tryding

Research output: Contribution to journalArticlepeer-review


A new approach to the low cycle fatigue problem, based on non-linear fracture mechanics, is investigated. The method is designed to predict final failure of engineering structures containing cracks that are small compared to the significant length dimensions of the structure. The suggested procedure is simple to apply and the failure load can be predicted for a moderately low number of major load applications. The method is confirmed by a large number of experimental tests. Different specimen sizes and types are investigated and by using a scaling factor the results can be given for each tested material in a comprehensive form, irrespective of specimen geometry and initial crack length. In the experiments steel and aluminium materials were used.
