This paper describes the integration of an ultrasonic-based non-destructive testing (NDT) with wireless sensor networks (WSNs) to continuously monitor material integrity during run-time. NDT is a technique that allows the examination of material properties without causing any damage to the material in the process. A wireless sensor network facilitates the collaborative effort to monitor a certa...

Manufacturing defects and discontinuities in a product are anomalies which can lead to severe damages may sometimes involve loss of life. These must be examined corrected before the goes into service. There two methods testing for viz. Destructive Testing Non-Destructive Testing. entails subjecting conditions that leads failure whereas (NDT) is process examining products way it retains its usef...

Non-destructive testing of objects and structures is a valuable tool, especially in cultural heritage where the preservation inspected sample vital importance. In this paper, decorative marquetry with three non-destructive (NDT) techniques: air-coupled ultrasound, X-ray micro-tomography, infrared thermography. Results from techniques were compared discussed. micro-tomography presented most deta...

corrosion of reinforcing steel and other embedded metals is the main cause of severe deterioration in reinforced concrete structures which subsequently imposes adverse effects on ultimate and serviceability limit state performance of the whole structure. in this paper, a new corrosion detection method for reinforced concrete beams, based on wavelet analysis is presented. to evaluate the capabil...

In the construction industry, non–destructive testing (NDT) methods are often used in field to inspect compressive strength of concrete. NDT do not cause damage existing structure and relatively economical. Two popular rebound hammer (RH) test ultrasonic pulse velocity (UPV) test. One major drawback RH UPV is that concrete estimations very accurate when comparing them results obtained from dest...

The role of non-destructive material characterization and NDT is changing at a rapid rate, continuing to evolve alongside the dramatic development of novel techniques based on the principles of high-resolution imaging. The modern use of advanced optical, thermal, ultrasonic, laser-ultrasound, acoustic emission, vibration, electro-magnetic, and X-ray techniques, etc., as well as refined measurem...

Several important technological and economic trends are shaping the research on non-destructive testing techniques. They include increasing computerisation and automation, fusion of different NDT methods, new market expansions, use of the techniques as a process control tool, and a proliferation of merges, consolidations and joint ventures. Other important factors such as the development of new...

The purpose of this paper is to review recent research on the applications of existing non-destructive testing (NDT) techniques, especially radio frequency (RF) NDT, for carbon-fibre reinforced plastics (CFRP) composites. Electromagnetic properties of CFRP composites that are associated with RF NDT are discussed first. The anisotropic characteristic of the conductivity and the relationship betw...

This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...

We examine non-destructive testing (NDT) techniques that characterize the interlayer bond quality of idealized 3-D printed concrete, simulating a layup bond, in-situ. An experimental study evaluates four NDT methods (x-ray radiography, ultrasonic pulse velocity (UPV), vibration resonance, and multi-element array ultrasonics) to idealized, layered concrete specimens simulate layers structure.
