Fatigue/reflection cracking

The ductility of asphalt is a measure of the flexibility of the asphalt and is expressed as the distance in centimeters that a standard briquette can be elongated before breaking (ASTM D-113, IP 32). Ductility is a combination of flow properties and reflects homogeneity, cohesion, and shear susceptibility it is an indication of fatigue life and cracking. [Pg.341]

The existence of the minimum must surely reflect the presence of competing fatigue mechanisms. It is proposed that the decrease of crack growth rates at low water contents reflects the ability of tightly bound water to increase fracture energy... [Pg.550]

It has been shown that fatigue life is influenced by the fatigue crack growth kinetics and is reflected through changes in A and n in the power-law representation, for... [Pg.115]

For hydride-forming alloys, such as titanium alloys, the crack growth response may exhibit strong temperature and frequency dependence that is also a function of K level. This dependence reflects the influence of strain, strain rate, and temperature on hydride formation and rupture [7,8]. Support for this response is provided by the early fatigue crack growth data on Ti-6Al-4V(Ti64) alloy in 0.6 M NaCl... [Pg.173]
