Comparison between Ultrasonic and Pulse - Radar Non - Destructive Testing Systems

چکیده
-This paper describes comparison between our developed two Non-Destructive Testing (NDT) system with ultrasonic method and pulse-radar method. These systems could provide information of embedded objects in concrete structure. First, we introduce these NDT systems. The raw output images of these methods keep us from understanding them. To overcome this problem, we apply fuzzy logic into them. Next, we compare these two developed systems to show how to select appropriate method for various cases. Consequently, pulse-radar system is good for general purpose, because this system needs no coupling medium. Ultrasonic system is appropriate for the purpose (e.g. to detect both embedded objects and cracks, to examine deeper area, and in case of gathering of reinforcing bars). We recommend that these two systems are complementally for realizing NDT system.

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...
متن کاملPrediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
متن کاملPulser for Piezoelectrics Transducers Used in Non-destructive Testing
In order to get, at the ultrasonic receiver input, a clear echo pulse, it is very important to apply on the transducer a short high amplitude pulse (hundreds of volts). The pulse frequency is low enough to allow the reception and processing of the informations received from the analysed material between two adjacent pulses, but high enough to ensure an integral control of the material. The piez...
متن کاملUse of Non-Destructive Ultrasonic Pulse Testing Methods in Evaluation of Brick Parameters
Currently, building industry uses non-destructive testing methods primarily for evaluation of concrete quality. Efficiency of ultrasonic pulse method (UPM) was proved in order to determine compressive strength of solid bricks (concrete, calcium silicate and burnt ones). Parameters obtained from UPM testing (such as ultrasonic pulse velocity, dynamic modulus of elasticity) are affected by shape/...
