Non-destructive testing (NDT) of engineering materials, components and structures has steadily increased in recent years at an unprecedented rate because of all-round thrust for improving material quality, component integrity and performance reliability. Ultrasonic testing is a versatile NDT method, which is applicable to most materials, metallic or non-metallic. The relevance of computed tomog...

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 ...

Non-destructive testing(NDT) adalah pengujian material untuk menentukan kualitas dan integritas atau elemen struktur tanpa memengaruhi kemampuan menjalannya fungsinya. NDT itu sendiri memiliki beberapa metode pengujian, yaitu radiograph testing, eddy current thermal penetrant ultrasonic visual testing. Metode curent biasanya digunakan melihat crack maupun mengetahui perbedaan suatu melalui nila...

Non-destructive testing (NDT) of aerospace structures has gained significant interest, given its non-destructive and economic inspection nature enabling future sustainable maintenance repair operations (MROs). NDT been applied to many different domains, there is a number such methods having their individual sensor technology characteristics, working principles, pros cons. Increasingly, approach...

In the last decades the development of very high speed trains in railway transportation requires new maintenance strategies. New trolleys equipped with innovative measuring systems have been employed for monitoring overhead lines (catenaries). Using this system gives two great advantages: i) the diagnose can be performed with a low level of breaking in railway traffic; ii) the monitoring can be...

The load-bearing capacity of pavement structures is a fundamental structural performance metric of transportation infrastructure networks in the context of safe and efficient movement of people and goods from one place to another. Non-destructive test (NDT) methods are typically employed to routinely evaluate the structural condition of pavement structures, their lifespan and the appropriate ma...

Adhesion in this system is one of the most important factors that affect reliability and durability repair. According to many standards guidelines, a pull-off test recommended for assessment bond quality repair systems. However, growing interest development non-destructive techniques (NDT) evaluation concrete structures recently noted. A majority NDT methods mentioned EN 1504-10 efficiency are ...

Eddy Current Techniques (ECT) for Non-Destructive Testing and Evaluation (NDT/NDE) of conducting materials is one of the most applicationoriented field of research within electromagnetics. In this work, a novel approach is proposed to classify defects in metallic plates in terms of their depth starting from a set of experimental measurements. The problem is solved by means of a system based on ...

Digital radiography is earning its place in the NDT market, as specialists realize this technology surpasses Film and Film Replacement. Portable digital Radiography provides many benefits to users. Fast images upon request for immediate analysis mean there is no compromise on image quality and no repositioning. Vidisco flat panel systems enable the reduction of working time and costs while enla...

We show that discrete tomography (DT) is suitable to increase the possible inspection size of single material oblong objects compared to filtered back projection (FBP) in non-destructive testing (NDT) with 2D X-ray computed tomography (CT). For such objects which are in one dimension larger than the maximum detectable material thickness limited view angles occur and FBP is not suitable for reco...
