Gauss-Markov-Potts models for images and its use in many image restoration and super-resolution problems have shown their effective use for Non Destructive Testing (NDT) applications. In this paper, we propose a 3D Gauss-Markov-Potts model for 3D CT for NDT applications. Thanks to this model, we are able to perform a joint reconstruction and segmentation of the object to control, which is very ...

4. Neutron and X-ray Tomography in Non-Destructive Testing (NDT): A new complex neutron-, gamma-, and X-ray three-dimensional computer tomography system suitable for experimental and industrial applications has been built at 10-MW Budapest research reactor site. A number of objects were investigated and tomographic projections were made. We study the optimal preprocessing steps and the optimal ...

This study sums up the authors recent works on steel Non-Destructive Testing and Evaluation achieved between 2000 and 2008. The main related items are the establishment of a first-order correlation between the thermal diffusivity and the Vickers hardness HV as a guide to set an NDT protocol to investigate steel strengthened surface performance. A special attention is confined toward carburized ...

The field of NDT is a very broad, interdisciplinary that plays critical role in evaluating the structural component and systems perform their function reliable manner. A review presented Non-Destructive testing methods for material characteristics, deformation materials without destroying material. These are important determining identifying discontinuity defects found on parts an object. There...

Measurement system analysis (MSA) technique is an important method which is used to analyze statistical discreteness and measurement capability of a measurement system, and also one of quality improvement techniques. The paper describes analysis principle and methods of repeatability and reproducibility (R&R) in MSA, introduces MSA techniques into the field of non-destructive testing (NDT). Bas...

One of the basic mechanisms of radiation embrittlement of steels and welds is due to matrix damage. Embrittlement results in a raise in the ductile-to-brittle transition temperature, which is normally used as indicator of the degradation status of the material. Other methods different than mechanical tests can be used to follow embrittlement like small punch test, non-destructive measurements o...

Reliable failure prediction methods are required for extending the range of applications of carbon-fiber-reinforced-polymers. In parallel, the development of non-destructive tests (NDT) for continuous health monitoring would result in structures of improved durability and safety. Carbon fibre-reinforced polymers (CFRP) have been investigated for the development of “smart” structures characteriz...

This study aims to develop combined methods with dual and triple use of different non-destructive test (NDT) examine the effectiveness these methods. For this purpose, nine high-strength concrete series were produced, destructive NDT applied samples on 3rd 90th days. Surface hardness, ultrasonic pulse velocity, penetration resistance considered from Analyses made response surface method using m...

Ground Penetrating Radar (GPR) is a geophysical method that has several applications in the field of civil engineering, one largest fields being evaluation technical state affected reinforced concrete structures by corrosion. In Cuba, this not been widely used as non destructive test (NDT), largely due to lack knowledge its potential engineering. This article performs critical analysis some inv...
