| Abstract: | The parameters of TiNi super elastic wire embedded in composites were selected,and its properties of stress strain resistance during phase transformation were measured.The results show that strain resistance of TiNi super elastic wire is nearly linear,can be applied for sensor information in composite structure health monitoring.The theory of structure health monitoring based on TiNi super elastic wire sensor network is introduced.Experimental specimens used in health monitoring were manufactured,and detailed research method was designed.Simulating test shows that the method is applicable. |
