| Abstract [eng] |
The objective of this thesis is determination of defects in honeycomb sandwich material using ultrasonic phased arrays. The computational parameters set back to conduct investigations on real-time experiments. The CIVA computer results are helps to obtain the desired parameters to follow the experimental estimation. The computer-aided design model was designed, and the finite element method simulation conducted to demonstrate the ultrasound wave propagation on the carbon fiber material with defect and without defect. The experimental analysis conducted and the defect on the sample was detected. The different frequency ranges 3.5 and 5 MHz with different transducers are helped to differentiate the defect positions and sizes. The different scan views are obtained to understand the defects in the sample. The conclusions are drawn the capability of a transducer and ultrasonic promising techniques which can identify defects precisely. |
