The wind-induced fatigue of guyed masts is a process of the wide-band stochastic fatigue.

The joint distribution of wind speed and direction is one of prime characters of wind load,the distribution function at the location of building have to be acquired before wind-induced fatigue life or reliability of the building is studied.

According to the basic theory of fatigue,we got the stress amplitude and the number of circulation by analyzing the process of the most dangerous element stress with the rain flow method and calculated the fatigue life of the windbreak based on the linear cumulative damage Miner theory by compiling the procedure of ANSYS wind-induced fatigue.

Analysis on vibration fatigue and heat transfer enhancement technology of shell and tube heat exchangers;

The results show that the fracture mode of blade is vibration fatigue and the main cause of initiation of fatigue crack is the mismatch between rabbet and tongue-and-groove.

An advanced global/local finite element modeling (FEM) technique combined with superelement technique was used to study SMT solder joint vibration fatigue on the basis of an example of Flip Chip assembly.

Study on Ice-induced Fatigue Characteristic of Jacket Platform;

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.
