TLDR
In this article, two ultrasonic transducers are used as transmitter and receiver to detect damage and performance for mechanical structures found in wide variety of application in various fields and the signal obtained from the receiver will be further processed.Abstract:
Structural health monitoring is the method of detecting damage and performance for mechanical structures found in wide variety of application in various fields. Ultrasonic examine is a regime for detection of defects in engineering structures. Here the block is used as a specimen under test. Two ultrasonic transducers are used as transmitter and receiver. The Signal obtained from the receiver will be further processed. Here the block undergoes two significant methods such as pulse echo and through transmission testing. From the data corresponding inference comparison methods is analysed.read more

Damage identification in aircraft composite structures: A case study using various non-destructive testing techniques
TL;DR: In this paper, the authors experimentally tested three composite structures made of glass fiber-reinforced plastic, hybrid composite with a core made of the same material and face sheets made of aluminum alloy and a carbon fiber reinforced plastic structure extracted from the vertical stabilizer of a military aircraft.
Structural Health Monitoring of a Smart Composite Bridge Using Guided Waves and Acoustic Emission Techniques
TL;DR: To access the structural integrity of the footbridge, two complementary monitoring strategies were presented in this paper: a real-time acoustic emission monitoring system to detect fibre breaks and a monitoring system using guided waves to evaluate the resin degradation.
