Reliable assessment procedures are an important aspect of maintenance concepts. Non-destructive testing (NDT) methods are an essential part of a variety of maintenance plans. Fracture mechanical assessments require knowledge of flaw dimensions, loads and material parameters. NDT methods are able to acquire information on all of these areas. However, it has to be considered that the level of det...

Non-destructive testing (NDT) as a part of many technologies includes various techniques for detecting undesirable random events accompanying industrial and operating processes. These NDT techniques must be adjusted to individual needs and materials. From this point of view it would be serviceable to dispose of a technique applicable for as much as possible testings and also e.g. NDT applicatio...

Nondestructive testing (NDT) system engineering is comprised of different technologies, primarily measurement physics, computing, electronics, mechanical engineering and automation. Significant progress in sensor physics, microelectronics and computing in the last decade will change both the quality and application of NDT. We present examples of intelligent sensor technologies and integrated, e...

In Germany, the last light water reactor (LWR) was put into service in 1989 (Neckar-2) [1], and due to the current political atmosphere no new LWRs are being considered for construction by the utilities at this time. Therefore, nondestructive testing (NDT) for new construction is no longer an attractive business, and is only required after component repair and/or component replacement. The tech...

This thesis is concerned with autonomous navigation of a robotic vehicle in a semi-structured environment. Starting from the low-level problem of range sensing and moving on to more complex tasks like spatial representation, registration and mapping, path planning and following, this dissertation aims at providing a consistent picture of an autonomous navigation system. A unifying concept throu...

At present the civil aerospace industry is undergoing its most rapid period of change in history, due to the large-scale move from metal to composite primary structures. This poses an immediate throughput challenge for the non-destructive testing (NDT) community on the production line where, initially, all composite primary structure will be inspected at manufacture. The background of composite...

Modern production of structural parts in the aeronautic industry is characterized by mechanically optimized structures that can be complicated to inspect due to complex geometries and/or complex materials. Developing NDT procedures is thus more challenging and could become costly without tools to help NDT design and performance predictions. Simulation is a major asset to help engineers to evalu...

Multi-information fusion is the trend of NDT equipments. This paper describes the principle, configuration and application of EMS-2003 —– a new device combining metal magnetic memory, eddy current and magnetic flux leakage testing techniques. By using the three complementary NDT techniques, we are able to make complete testing and analysis on early damages and established defects in in-service ...

This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...
