Gauss-Markov-Potts models for images and its use in many image restoration, super-resolution and Computed Tomography (CT) 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 contro...

Advanced manufacturing and new energy systems are presenting a wide variety of challenges for nondestructive testing and evaluation (NDT/NDE). This paper discusses the state of the art, needs and opportunities for NDE to provide reliable, effective and economic inspection and monitoring for energy systems. It introduces issues of materials, defects and allowables, the evolution of advanced NDT ...

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...

in this paper a new method for nondestructive testing or nondestructive evaluation is proposed for glass-epoxy composite. for this purpose, impact-echo is used to evaluate the properties of composite materials, detecting internal defects and thickness measurement. in the impact-echo method a steel ball impacts on a composite plate and generates stress waves or p-waves which will be transferred ...

Nondestructive testing (NDT) is an advanced and commonly used technique in tunnel engineering quality inspection. To achieve good application of nondestructive technology, its main inspection strategy analyzed, including the significance applying technology inspection, applied test analysis, analysis strategy. The analyses this paper are done hopes providing scientific reference for utilization...

The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...
