Fatigue Cracking of Fiber-Reinforced Titanium Matrix Composites

CODEN: JCTRER

Abstract

The fatigue crack growth behavior of a unidirectional SCS-6-fiber-reinforced Ti-6Al-2Sn-4Zr-2Mo composite has been characterized. A fatigue cracking map for several unidirectional SCS-6-fiber-reinforced titanium and titanium aluminide composites under tension-tension fatigue loading has been developed. The map is constructed based upon the fiber strength to interfacial shear strength ratio versus the applied maximum stress intensity factor. Also, the effect of fiber bridging on the effective crack driving force in the matrix is analyzed using the shear-lag model and finite element analysis.
