Fatigue crack propagation can considerably reduce the life of components, leading to sudden failures. This paper provides a method for fatigue prediction based on ultrasonic non-destructive inspection applied Al 2024 T3 material.

In non destructive testing of materials, the ultrasonic imagery is a field in full rise. Indeed , more than one convivial representation of the results , the operations of detection , localization and sizing of the defects can be carried out automatically by the analysis of synthesized images. The problem breaks up in general into a phase of preprocessing to only limit the quantity of informati...

In the first and second stage nuclear program of Department of Atomic Energy (DAE), technologies are matured for Pressurised Heavy Water Reactors (PHWRs) and Sodium-Cooled Fast Breeder Reactors (FBRs). Pre-service-Inspection (PSI), In-Service-Inspection (ISI) and Post-Irradiation-Examination (PIE) procedures are carried out for mechanical components and structures/assemblies of these reactors, ...

The increasing use in the industries of composite materials implies finding a suitable way for testing and evaluating them. Non-destructive testing by ultrasounds is an appropriate method to detect defects in this type of materials, however, because of their structure it is required to find the most applicable and accurate process for detecting flaws and anomalies in them. For conventional ultr...

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. Th...

Non-destructive testing(NDT) adalah pengujian material untuk menentukan kualitas dan integritas atau elemen struktur tanpa memengaruhi kemampuan menjalannya fungsinya. NDT itu sendiri memiliki beberapa metode pengujian, yaitu radiograph testing, eddy current thermal penetrant ultrasonic visual testing. Metode curent biasanya digunakan melihat crack maupun mengetahui perbedaan suatu melalui nila...
