Structural Health Monitoring versus Non Destructive Evaluation

Many of the existing NDE techniques have been customized for specific SHM uses by integrating sensors and actuators inside the structure to be monitored. Following are the perceptible advantages of SHM over NDE:

• Reduced inspection down time.
  
  
• Elimination of component tear down and human involvement.
  
  
• Potential prevention of failure during operation.
  
  
• Enabling new possibilities for maintenance concepts influencing design and assembly technologies leading to both maintenance and weight saving benefits.
