Take a typical production riser as an example to calculate,the results show that wave-induced fatigue damage on riser top location and diameter of the parallel position is worse than the other location.

Being considered as a dominant factor for its failures, the field-induced fatigue of piezoelectric ceramics is a gradual degradation of piezoelectric properties under applied cyclic loading and becomes a hot topic in the world in recent years.

The experimental research for electric fatigue of ferroelectric ceramic;

Influence of joint distribution of wind speed and winddirection on wind-induced fatigue life reliability

The guyed mast is an extensive used tall and slender structure,which tends to generate wind-induced fatigue rupture that may cause the collapse of the whole guyed mast.
