| Abstract: | In this work, the benefits from the blending between micro-structural fracture mechanics and elasto-plastic fracture mechanics in the analysis of fatigue damage in titanium metal matrix composites (TMCs) is presented. The efficiency of interfacial debonding and fibre bridging (FB) are shown not only to control crack growth but also to be responsible for severe crack growth changes taking place throughout the material's response under fatigue. A possible way to extract answers about the fatigue threshold, the operational life of the material and finally the fracture toughness is given in detail. |
