Application of time reverse modeling on ultrasonic non-destructive testing of concrete

Measurement and Modelling of the Rubber Resilience based on Ultrasonic Non-destructive Testing in Tires

In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...

Ultrasonic non destructive testing based on sparse deconvolution

The acoustic modality yields non destructive testing techniques of choice for indepth investigation. Given a precise model of acoustic wave propagation in materials of possibly complex structures, acoustical imaging amounts to the so-called acoustic wave inversion. A less ambitious approach consists in processing pulse-echo data (typically, Aor B-scans) to detect localised echoes with the maxim...

A high-power ultrasonic pulser-receiver for concrete non- destructive testing

Artificial neural networks for non destructive testing of concrete structures

In this paper, the determination of defects in concrete structures using an ultrasound technique is discussed. A diagnostic model for concrete pillars by means of Multi Layer Perceptron neural networks is developed to locate and classify the defects. Finite Elements numerical techniques have been used to model a concrete pillar of specified size (i.e., rectangular cross section and 2 meters in ...
