Non Destructive Testing applied to railway axles is performed both in production and in maintenance. During production, NDT is carried out at different stages adopting different techniques, while during maintenance (in-service inspection) only ultrasonic testing is usually carried out. The present paper is focused on some aspects of calibration related to the in-service inspection of railway ax...

Spatial variability of concrete is an important characteristic, which qualifies the non-homogeneity of concrete properties within structural components. Assessing it can be of great interest for damaged areas localization and for reliability analysis of structures. A two-stage experimental program was carried out using non-destructive testing (NDT) on laboratory concrete slabs in outdoor enviro...

Investment cast aerospace components are prone to defects related to solidification process. The hollow columnar-grained aero engine Vane casting, being discussed in this paper, suffers further from extraneous defects such as inclusions, core shift and resultant dimensional deviations. Due to its design complexity and stringent specifications, non-destructive evaluation (NDE) of this component ...

As of recent, non-destructive testing (NDT) has been used more frequently to evaluate and assess the condition buildings [...]

In the construction industry, non-destructive testing (NDT) methods are gaining more popularity for their ability to examine the in-situ component properties without damaging the structure. One of the most common NDTs for measuring the concrete compressive strength on site is the Rebound Hammer Test. Using the rebound value obtained from the test hammer, the concrete compressive strength can be...

In situ resource utilization (ISRU) and automation are necessary. The logical first step of intention is to focus on our neighbor, the Moon, first. This work aims expand knowledge lunar aggregate simulant (LAS) based ilmenite rock, which available in Central Europe. Prismatic mortar samples were prepared standard sand LAS. measurements conducted using several different destructive (DT) strength...

Corrosion of reinforced concrete (RC) structures has been one of the major causes of structural failure. Early detection of the corrosion process could help limit the location and the extent of necessary repairs or replacement, as well as reduce the cost associated with rehabilitation work. Non-destructive testing (NDT) methods have been found to be useful for in-situ evaluation of steel corros...

Historically, little effort had been made to match patch repairs culturally significant reinforced concrete structures so that they are effective and sustain the aesthetic values of structure. The collaborative research project, Performance Evaluation Patch Repairs on Historic Concrete Structures (PEPS), being undertaken by Getty Conservation Institute (GCI), England (HE) Laboratoire de Recherc...

A reliable maintenance system is critical to maintain an acceptable level of profit and competition. One of those techniques that are gaining a lot of interest in the manufacturing field is Non-Destructive Testing (NDT). In this work we propose an approach to integrate NDT into the development process of intelligent manufacturing systems. We propose an extension of ANEMONA, a multi-agent based ...

Automation of non-destructive testing (NDT) of engineering components and structures represents one of the strategic objectives of many industries. It enables increases in accuracy, precision and speed of inspection while reducing production time and associated labour costs in contrast to manual inspection. The use of robots can provide additional flexibility and autonomy to automated NDT. Auto...
