Paper Title:
Fatigue Crack Propagation of Magnesium Alloy and Aluminum Alloy in Biaxial Stress Fields
  Abstract

In this research, fatigue crack propagation tests of magnesium alloy AZ31B and aluminum alloy 2024T3 were conducted under conditions of biaxial and uniaxial loading by using a cruciform specimen in a biaxial fatigue machine, in order to investigate the effect of non-singular stress cycling. From these comprehensive experiments, in the magnesium alloy, the remarkable effect was found in the specific biaxial load stress ratio RB (= σx 0/σy 0) on KI-da/dN relation. On the other hand, in the aluminum alloy, it was confirmed that there is no influence of a RB on KI-da/dN relation.
