Overview of Non-Destructive Testing (NDT) Methods of Materials Evaluation

The opening paper of this symposium was dedicated to an overview of the existing state of the practice and the advantages and limitations of non-destructive testing methods for the evaluation of historic materials of construction. The methods discussed in this paper include the state of the practice in visual, rebound, penetration, and ultrasound methods, as well as the physical measurement of ...

Synthetic Focusing Aperture Techniques for Non-destructive Testing of Materials

Synthetic Aperture Focusing Technique imaging has became a popular tool in the field of non-destructive testing in the past years. The acquisition procedure consists in collecting the data after activating elements one by one. The reconstructed object is then computed by adding the contribution of each channel, selecting the proper time delay values. It is the principle of the well-known delay ...

Free Vibration Analysis of Functionally Graded Materials Non-uniform Beams

In this article, nonuniformity effects on free vibration analysis of functionally graded beams is discussed. variation in material properties is modeled after Powerlaw and exponential models and the non-uniformity is assumed to be exponentially varying in the width along the beams with constant thickness. Analytical solution is achieved for free vibration with simply supported conditions. It is...

Fuzzy Logic for Non-destructive Testing for Various Composite Materials

This paper presents the use of artificial intelligence techniques such as fuzzy logic for nondestructive X-ray testing of various products. The original presented algorithm proposes the defect presence testing in two stages in the radiographic image obtained from the inspected product. The first stage of the algorithm checks whether a possible defect (an area from the radiographic image) corres...
