The importance of Non-Destructive Testing (NDT) to check the integrity of materials in different fields of industry has increased significantly in recent years. Actually, industry demands NDT methods that allow fast (preferably non-contact) detection and localization of early-stage defects with easy-to-interpret results, so that even a non-expert field worker can carry out the testing. The main...

Non destructive monitoring of prestressed civil structures such as bridges, dams, nuclear power plants, etc. is extremely important to ensure security of users and environment. This challenging task brings together the non destructive testing (NDT) and civil engineering (CE) communities. As a part of this relationship, this paper deals with a non destructive procedure for stress levels evaluati...

Abstract As a popular nondestructive testing (NDT) technique, thermal imaging test demonstrates competitive performance in crack detection, especially for detecting subsurface cracks. In test, the temperature of area is higher than that non-crack during NDT process. By extracting features image sequences, curve each spatial point employed detection. Nevertheless, quality images influenced by no...

Weathering profile characterization is one of the significant information in interpretation condition rock. In addition, tropical climate Malaysia causes deep–seated weathering phenomena granitic The identification granite can be made using in–situ Schmidt hammer rebound test which non–destructive tests (NDT) that widely used. this study, carried out on rock Paya Terubong, Pulau Pinang. Based s...

Subsurface imaging of civil structures is a subject of growing interest because of the need check the integrity of buildings, roads, and bridges in a non-invasive (and certainly nondestructive way). In this framework, this study is aimed at presenting a microwave imaging technique for crack or failure detection. The proposed approach is based on a numerically computed Green's function and on an...

The operational safety and reliability of an airplane must be integral part its design. use suitable materials that pass material certification tests is very important for a new aircraft next testing specific samples, sub-components, components such as the aileron. paper deals with non-destructive evaluation composite primary structural fatigue in accordance damage tolerance philosophy consider...
