Experiments Concerning Brittle, Ductile, and Environmentally Controlled Fatigue Crack Growth
SourceVarious experiments were carried out in copper and Fe-3Si under as simple as possible conditions in order to get unequivocal information about the mechanisms which are relevant for crack initiation and propagation. New results are reported about the conditions for Stage I crack growth. It is pointed out how extrusion-intrusion pairs can form as a consequence on Stage I cracks. Furthermore, the strain distribution around Stage II cracks is described in detail. Environmental effects on Stage I and Stage II crack propagation are reported and evidence is presented for rewelding during the compressive phases. Finally, a new experimental approach to study brittle crack initiation at plastified cracks is described.
