The imaging of structures with a complex material composition and geometry is still challenge in the field non-destructive testing (NDT). In this study, non-invasive technique proposed for inspection both cultural heritage natural fiber composites. combines surface information provided by infrared thermography (IRT) internal structure retrieved terahertz (THz) time-domain spectroscopy using an ...

The wire and arc additive manufacturing (WAAM) process enables the creation repair of complex structures based on successive deposition fed metal in form a that is fused with an electric then solidifies. high number depositions required to create or parts increases likelihood defect formation. If these are reliably detected during manufacturing, timely correction possible. However, temperatures...

Currently, radiometric thermography image has been explored adequately as alternative advance Non-Destructive Testing (NDT) especially for early detection analysis in various applications. Systematic calibration, higher spatial resolution and high degree order processing, imagery potential to be used concrete structure defect detection. Therefore, this study is carried out examine the on bridge...

Thermographic flash-pulse inspection is one of popular methods non-destructive testing (NDT) materials. Despite the automation NDT methods, most them are based on visual inspections and results these influenced by skills operators. The repeatability reproducibility (R&R) therefore more important compared to exact gauge-type methods. This study was focused statistical evaluation flash pulse ...

Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...

non-destructive testing & evaluation methods are developed to inspect and investigate materialsand structures. ultrasonic testing is an ndt method can be used for measuring the thickness ofobjects, as one of its significant applications. the objective of this paper is designing and applyingan intelligent ut fuzzy control system for evaluating the thickness of thin metal objects in a rangeof...

The effective length of soil nails is one the critical parameters ensuring reinforcing effect, and its accurate estimation great significance for safety slope deep foundation pit supporting projects. Traditional quality insurance methods, such as nail pullout tests, suffer from a series drawbacks including being destructive, high cost, time-consuming. In contrast, non-destructive testing (NDT) ...
