Fatigue is one of the most important failure modes to be considered in mechanical and structural design. It has been stated that fatigue accounts for more than 80% of all observed service failures in mechanical and structural systems. Moreover, fatigue and fracture failures are often catastrophic; they may come without warning and may cause significant property damage, as well as loss of life. Many cases of critical component fractures are observed in applications in which failures previously had not been encountered. |
