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 کاملDevelopment of efficient hybrid finite element modelling for simulation of ultrasonic Non-Destructive Evaluation
The measurement and numerical modelling of ultrasonic wave scattering is essential for detecting complex defects in safety critical components for engineering structures across a range of industries. Fast and accurate numerical modelling to simulate candidate set ups for Non-Destructive Evaluation (NDE) is attractive as it both improves confidence in the inspection results and reduces the cost ...
متن کاملUltrasonic technique for non-destructive quality evaluation of oranges
6 Common techniques to monitor the quality of fruit at the time of harvest and in storage typically rely on destructive methods to measure physical properties such as firmness and hydration. The complex, inhomogeneous composition of most fruit mean that non-destructive ultrasonic methods for quality evaluation of fruit has typically been unsuccessful. A novel ultrasound method was developed whi...
متن کاملPulse Compression Ultrasonic Non Destructive Evaluation of Thick Polymer Samples
The use of ultrasonic signals at sub-MHz frequencies for Non Destructive Evaluation of thick polymer samples is described. It will be shown that the combination of low-frequency coded signals such as chirps, together with appropriate signal processing methods such as pulse compression, can provide a powerful tool for ultrasonic NDE. To achieve this goal, it is essential that the measurement sys...
متن کاملUltrasonic Non-destructive Evaluation of Titanium Diffusion Bonds
Diffusion bonds offer several advantages over alternative welding methods, including the ability to produce near-net shapes and achieve almost parent metal strength. However, voids remnant from the joining process can be tens of microns in their lateral dimension, making them difficult to detect with conventional pulse-echo immersion inspection at any significant metal depth. In titanium the in...
