The development of methods for the Non-Destructive Evaluation (NDE) of concrete and masonry structures has made considerable progress in the past two decades. Technology and knowledge transfer from other areas such as materials testing and medicine has been the main source for innovation, supported through multidisciplinary research by scientists, technicians and support personnel. A versatile ...

Cracking and deterioration of concrete are the leading causes of a premature failing of reinforced concrete structures. To assess the condition of concrete, a variety of destructive and non-destructive testing methods have been developed. From these two methods, the non-destructive testing (NDT) is a more favorable (albeit more challenging) option since the tested target is left undamaged. The ...

Purpose The purpose of this paper is to describe the approach for design cowlings a new fast helicopter from perspective airworthiness requirements regarding high-speed impact resistance. Design/methodology/approach Validated numerical simulation was applied flat and simple curved test panels. High-speed camera measurement non-destructive testing (NDT) results were used verification models. fin...

Acoustic sonic and ultrasonic resonance analysis is a new non-destructive testing technique that allows 100% testing of a wide range of test objects quickly and at low cost. After an impact, a specimen vibrates in certain characteristic modes and frequencies that can be measured by a microphone or laser vibrometer. Typical faults that can be detected are cracks, cavities, detached layers, mater...

This research is devoted to investigate relationship between both Ultrasonic Pulse Velocity and Rebound Number (Hammer Test) with cube compressive strength also study the effect of steel reinforcement on these relationships. A was carried out 32 scale model reinforced concrete elements. Non destructive testing campaign (mainly ultrasonic rebound hammer tests) made same About 72 cubes (15 X 15 X...

The application of the neuro-fuzzy inference system to predict the compressive strength of concrete is presented in this study. The adaptive neuro-fuzzy inference system (ANFIS) is introduced for training and testing the data sets consisting of various parameters. To investigate the influence of various parameters which affect the compressive strength, 1551 data pairs are collected from the tec...

The significance of non-destructive testing (NDT) methods cannot be overstated as they help to evaluate the properties a material without damaging/fracturing it. However, their applicability is dependent on ability provide reliable correlation with destructive tests such tensile and flexural. This becomes more problematic when not homogeneous, case parts manufactured using popular additive manu...

Use of Non Destructive Testing (NDT) technique during aircraft maintenance operations is increasing in the last years as well as the tools to perform these inspections are widening their field of application. Damage tolerance design approach has been selected by aeronautic industry for the last years also thanking to the most modern NDT capabilities, like ultrasound and thermography, which have...
