Description of short fatigue crack propagation under low cycle fatigue regime
Original language description
Measurement of the short fatigue crack propagation can come across a lot of difficulties from the experimental point of view and interpretation of the results is also sometimes controversial. For simplicity, usual description of the short cracks is based on linear elastic fracture mechanics (using the concept of stress intensity factor). In this case, significant differences between short cracks and long cracks are usually presented. Most of the discrepancies are simply given by non-validity of the linear elastic fracture mechanics approach. In our case of physically short fatigue cracks the level of applied stress is close to cyclic yield stress of the material and, due to large amount of plasticity, conditions of linear elastic fracture mechanics are not satisfied. As a consequence, non-linear elastic plastic fracture mechanics is used for description of the short crack behavior in this article. Concept based on plastic part of J-integral is proposed for the description of the short crack behavior and data obtained for different strain amplitudes are compared. This concept is validated on experimental data obtained on steel 316L.
