| Abstract |
Mode II fatigue crack growth tests under a superimposed static compression stress field were made using a newly developed apparatus, in order to establish a test method to obtain the intrinsic mode II crack growth resistance of steels. The difference between the crack growth in simple mode II loading and the crack growth in rolling contact fatigue is, we suppose, whether or not there is a superimposed compression stress. Some preliminary results on da/dN-ΔK_(II) relations have been obtained by using this apparatus on a steel and aluminium alloys. Subsurface fatigue crack growth in contact rolling fatigue were successfully simulated by this testing system. |
