In the massive labor intensity and fatigue measurement experiments,we discovered a quite big contradiction existence in the experiment psychology parameter s test result to the fatigue theory.

The labor intensity and the fatigue are important contents of ergonomics,the labor intensity and the fatigue measurement experiment supports this content greatly.

Research progress on fatigue assessment of welded joints by local approaches;

Research progress on fatigue assessment of welded joints based on structural hot spot stress;

The volumetric approach (VA) was applied to the fatigue assessment of SAF2205 duplex stainless steel welded joints with two types of geometrical modes, and its feasibility and the effect of the finite element calculation on this method were discussed.

3 Process Piping, some views on the questions about the flexibility analysis of the process piping including the relationship between flexibility analysis and fatigue evaluation, and whether the effect of pressure was included in the flexibility analysis or not etc.

According to the characteristic of helicopter load,a full range safe S-N curve formula suitable for helicopter fatigue evaluation is presented,and a method for getting safe S-N curve from median S-N curve is provided on the basis of 3-parameter S-N curve formula stromeyer equation in common use.
