摘要：

The fatigue-life (traction-traction only) is experimentally studied mainly for pseudoelastic NiTi wire of 2.46 mm of diameter for eventual application in damping of structures under wind or rain. Thermal effects are highly relevant in determining the fatigue-life. The results shows that the fracture level overcomes 130000 cycles when the moving air is used for cooling. When the number of working cycles overcomes 30000, the frictional energy decreases 40% vs. N roughly with an exponential behavior.
