Abstract:
The impact-echo method, which is to evaluate the integrity of concrete and masonry structures nondestructively, is an excellent method in practical applications, and provides a high quality of structural integrity assessment. However, in the case of multi-layered systems in which each layer has different stiffness, the impact-echo method may lack reliability in thickness evaluation, which demands improvement of the impact-echo method. This study was first dedicated to the understanding of stress-wave propagation in the impact-echo test, and secondly, the reliability of the impact-echo method was investigated through the numerical simulation of the impact-echo test. The investigation included the research on influencing factors such as stiffness contrast between layers and receiver location. Finally, the research in this paper led to the development of the phase-difference response (PDR) method, based on the frequency response between two receivers deployed in a line with an impact source.

Abstract:
To identify shield grouting quality based on impact echo method, an impact echo test of segment-grouting (SG) test piece was carried out to explore effect of acoustic impedance of grouting layers and grouting defects on impact echo law. A finite element numerical simulation on the impact echo process was implemented. Test results and simulation results were compared. Results demonstrated that, under some working conditions, finite element simulation results and test results both agree with theoretical values. The acoustic impedance ratio of SG material influenced the echo characteristics significantly. But thickness frequency could not be detected under some working conditions because the reflected energy is weak. Frequency feature under grouting defects was more complicated than that under no grouting defects.

Abstract:
The ultrasonic method and the impact-echo method are two kinds of nondestructive test method (NDT), which are widely used, not only for concrete component, but for masonry structures. However, it is hard to detect the flaw in the concrete composite component if only with one kind of detection method. In this study, the principle of ultrasonic method and impact-echo method are outlined. And an attempt of a new method is taken, that Ultrasonic method together with Impact-echo method is used in detecting the deflection in Concrete Composite Component. It is proved that the result of this new method is more accurate and stable than that of only using ultrasonic method or impact-echo method. Introduction Introduction

Abstract:
With the large-scale application of the prestressed concrete structure, the quality of the concrete component defects and pipeline grouting has increasingly become the focus of attention. The impact-echo scanner uses the nature of wave, which pass though different media at different velocities, to distinguish internal defects of concrete, pipe filling density and so on. In this paper, using the impact-echo method to detect the concrete block with prefabricated defects of shape, location, and size explores the effect of defect properties, parameter settings and detection environment to impact-echo preliminarily and also explores the relationship of pipeline filling status and impact-echo image. Based on this study, the article raised the problem met during this non-destructive testing methods applied to engineering, and accumulated a certain amount of available engineering data. The experiment results show that using the impact-echo method to identify the defects of concrete components and to test the quality of pipeline grouting is a more convenient and effective non-destructive testing method. Especially, with the radar method in the pipeline grouting quality inspection which complement each other to make up for the shortcomings the lightning wave in case of the metal medium total reflection phenomenon, cannot detect metal pipe grouting plumpness.

Abstract:
Nondestructive testing of concrete for maintenance purposes is the focus of this thesis. The application of a new nondestructive testing technique known as impact-echo was examined. The technique is based on transient stress wave propagation for the detection of defects in concrete, as well as measuring the setting time, early age strength, and elastic properties. Impact-echo functions by a mechanical impact, where stress pulses are generated in the test subject. The stress pulses undergo multiple reflections between the top and bottom of concrete layers. The surface displacements are recorded and the frequency of the successive arrivals of the reflected pulses is determined. Thus, knowing the thickness of a given layer, together with the measured frequencies, P- and S-wave velocities can be calculated. If on the other hand, the thickness is unknown, the time-distance graph of the primary surface wave arrivals could be used to calculate the thickness. The position of the impact source relative to the receiver must be selected in such a way as to detect P- and S-waves at their maximum reflection amplitude. In this study, defects were detected using the reflected P-waves from their top surfaces. In addition, the change in elastic moduli of various types of concrete mixes was monitored for a 30-day period by measuring P- and S-wave velocities. The impact-echo elastic moduli were then compared with static and dynamic values obtained by standard methods in order to assess their accuracy.

Abstract:
Le patrimoine d’ouvrage d’art Européen et en particulier français est vieillissant. Pour pouvoir le conserver, il est nécessaire d’établir un ‘état de santé’ de ces ouvrages en les auscultant. Afin de ne pas les dégrader lors de l’auscultation des méthodes de contrôle non destructifs (CND) doivent être utilisées. Nous nous sommes intéressés en particulier, à une méthode connue sous le nom d’Impact-Echo. La pathologie qui a retenu notre attention concerne les vides ou les défauts pouvant être situés dans le remplissage des ponts en maçonnerie, au-delà des voûtes ou des murs de têtes. Afin de tirer le meilleur profit de la méthode d’auscultation, une étude numérique permettant de simuler un Essai Impact-Echo sur une structure sous forme de plaque bicouche contenant un défaut est développée. Devant la difficulté d’interprétation des résultats issus de cette simulation, un plan d’expériences factoriel numériques est introduit. Pour ce plan d’expériences quatre facteurs sont retenus. Deux facteurs liés la géométrie de la structure e1 et d, un facteur lié aux matériaux composant la structures R et un facteur purement numérique . D’autres variables de sortie, autre que la lecture de la position du pic, sont introduites. A l’issue de ce plan d’expériences, nous avons pu dégager des relations, qui ont permis de lier les facteurs d’entrée aux différentes variables de sortie. Ces relations ont été testées, dans un premier temps, sur les données ayant servi à les établir. Une compagne expérimentale a été introduite afin de valider la simulation numérique. Pour cette validation, nous avons tenté d’exploiter les essais de la compagne expérimentale à l’aide des différentes relations obtenues du plan d’expériences numériques
The heritage of European and particularly French infrastructure is aging. To be able to preserve it, it is necessary to establish a "state of health" of these works by auscultation. In order not to degrade them during the auscultation, non-destructive testing (NDT) methods must be used. We were particularly interested in a method known as the Impact-Echo method. The pathology that caught our attention concerns voids or defects that may be located in the filling of masonry bridges, beyond the vaults or the head walls. In order to make the most of the auscultation method, a numerical study to simulate an Impact-Echo test on a bilayer structure containing a defect is developed. Faced with the difficulty of interpreting the results from this simulation, a numerical factorial design of experiments is introduced. For this experimental design four factors are retained. Two factors linked to the geometry of the structure e1 and d, a factor linked to the materials composing the structures R and a purely numerical factor . Other output variables, other than reading the peak position, are introduced. At the end of this experimental design, we were able to identify relations, which made it possible to link the input factors to the different output variables. These relations were first tested on the data used to establish them. An experimental campaign was introduced in order to validate the numerical simulation. For this validation, we tried to exploit the trials of the experimental companion using the different relations obtained from the numerical factorial design of the experiment

Abstract:
Traditionally, destructive methods such as coring are used for the condition assessment of an existing concrete structure. Although these methods may yield valid data about the corresponding concrete section, they are quite expensive and time consuming. More important than these, destructive methods damage the structure being investigated and these points usually become focal points for further deterioration. For all these reasons, only a few samples can be collected from a structure and this results in a poor representation of the complete structure. The impact-echo technique is one of the most suitable non-destructive test methods that may be used on concrete for thickness determination or for investigation of possible delaminations in the internal parts of a concrete structure without damaging the surface. It has been observed that reliable results can be obtained quickly. Unlike pulse-echo tests which are commonly used on steel, testing a heterogeneous material like concrete requires the use of low frequency sound waves as in impact-echo, in order to mitigate the effects of paste-aggregate interfaces or small air voids. This method may be used to locate internal cracks or large air voids existing in concrete. It is known that impact-echo has been used successfully on structures with varying geometries and various purposes such as evaluation of concrete pavements, retaining walls and other reinforced concrete sections. Besides the investigation of the internal state, it may also be used when the other side of the section cannot be reached, as in the case of concrete pavements, in order to find the thickness of the section. This is especially important for quality control and for cost calculations. Research conducted in this thesis study was concentrated on the thickness determination of existing concrete pavement sections, produced in the laboratory with dimensions of 1500 x 2000 mm four and varying thicknesses, and the accuracy associated with these results. In order to correctly determine the sensitivity, several other parameters were investigated and optimum ranges were determined for these to be used while on a field test. Among these factors were the steel impactor size, accuracy related to the data acquisition, distance between the impact point and the transducer and the location of the test point. Finally, the accuracy of the impact-echo method for concrete pavement applications was studied. By observing the large number of data points collected, it was found out that an average error of 1.5% exists for a single impact-echo reading regardless of section thickness, but this value reduces to 0.6% when the average of all test results is used while determining pavement thickness. Results of this study show that the impact-echo technique is reliable and may be used with success for the thickness determination of concrete pavements and for locating internal voids.

Abstract:
This thesis presents the development and validation of a new wireless Impact Echo (IE) system for condition assessment of reinforced concrete slabs. The new IE prototype was compared with other commercially available non-destructive testing (NDT) devices used for similar purposes, namely Ground-Penetrating Radar (GPR) and Ultrasonic Pulse Echo (UPE). Monitoring and structural inspections are critical to effective management of civil infrastructure and NDTs can enhance the quality of condition assessments by providing objective visualizations of the interior of a structural element. The IE method, first developed in the 1980s, has seen few advancements in the last 20 years. The method has been standardized and used on site, but the underlying technology has become outdated. The data obtained from the transducer is difficult to interpret and requires a computer to post-process it before being usable, thus limiting the direct feedback of the method when conducting tests on-site. Because of those limitations and the test being relatively more time consuming than other alternatives, the method is lacking in usability. A new prototype IE device was designed and built by the project industry partner, FPrimeC Solutions. The methodology followed the traditional approach, but it was designed to work with today’s technology. The device is operated wirelessly via a Bluetooth connection, uses smaller-sized electronic components, and connects with a user-friendly interface on a small tablet to set-up the tests and compute the results immediately. The first part of the project focused on product development by testing iterations of the prototype and providing user feedback to improve the device and accompanying software. The second part of the project aimed to validate the new technology using a set of three large reinforced concrete slabs containing artificial defects. The studied points of interest were sound concrete, effect of boundaries and steel reinforcements, vertical cracks, presence of a hollow conduit, artificial voids and delamination. The IE results were also compared with those from commercial GPR and UPE devices. GPR was found to be the quickest method by far, although the results gathered seemed to be limited by the presence of steel reinforcement and also failed to locate certain defects. UPE was a bit slower than GPR, but was generally able to locate more accurately the artificial flaws created in the test specimens. The results showed poor definition of the flaws making it difficult sometimes to properly locate them. The UPE results also seemed to be negatively affected by the presence of reinforcement which were causing frequent abnormal values. Lastly, the IE method was used. This method was greatly improved during the first phase, but it is still a time-consuming method. The value of the data, however, has great potential when compared to the other options. It accurately located most of the flaws generated and was practically unaffected by the presence of steel reinforcing bars. Also, with further analysis of the data, it was possible to determine the depth of some of the flaws accurately. Due to the time-consuming testing phase and the longer analysis of the data required to obtain the higher quality of results, this study suggests that IE is not likely to be the best choice for a general inspection of a large area (depending on the nature of the information needed). Rather, it is suggested to first conduct a general review of the structure using a quicker method like GPR to locate the problematic areas. After that, refining the grid at key locations to test with IE should provide the best quality of data in a reasonable amount of time.

Abstract:
A force that is applied dynamically in a short period of time is called an impact force (shock wave). Due to the concentrated application of force on a small area in a fraction of a second, unique applications have emerged that other types of loadings are not capable of performing. Explosions, an impact of a hammer, impact of waves on a shore wall, or the collision of two automobiles are examples where impact waves occur. In this research the effects of impact on solid materials and the motion of stress waves due to the impact are studied and some of their industrial applications are described.   The primary objective of this work is further development of some elastic and plastic impact wave methods, aiming to reduce the energy consumption of explosive welding (EXW) as well as the cost of NDT technologies. Many numerical simulations and a vast amount of experimental work were employed to reach this goal.   The impact wave creates elastic deformations that move the particles of the body. In this research we focused on dimensional measurement by calculating the time of wave travel between the source of energy and a discontinuity in the part studied. The impact echo (IE) method can be used for determining the location and extent of all kinds of flaws, such as cracks, de-lamination, holes and de-bonding in concrete structures, columns and hollow cylinders with different cross-sections and materials. In the present study, simulation of the impact-echo method was carried out numerically using direct and indirect methods. In the direct method a steel ball directly impacts on the upper surface of a concrete plate-like structure, whereas in the indirect method the impact impulse transmits to the concrete plate via a steel bar, in order to adapt the method for situations where there is no access to the plate being measured. In each method a two-dimensional finite element analysis (in axisymmetric geometry) was performed for the thickness measurement of concrete plates using the LS-DYNA program. Numerical results are presented for different values of plate thickness and different projectile speeds for both the direct and the indirect method and the indirect results are validated by comparison with the results obtained by the direct method. The method was validated against experimental measurements.   A high energy impact wave produces plastic deformations in metals. In this research explosive welding was studied as an application of high energy impact waves. A new method for joining different, non-compatible metals (Al and Cu-based materials) was introduced. This method may be extended for use in offshore applications. Many 3-D numerical simulations were performed using the ABAQUS explicit commercial software. The model was validated against experimental measurements.   The outcome of this research work could be summarized as follows: a)  Introducing an indirect IE method in NDT technology for thickness measurement in particularly inaccessible structures. b)  Introducing a new, grooved method in EXW technology to join surfaces made of different materials, in particular Al-Cu joints. The results could be employed to reduce the energy consumption and cost associated with EXW and IE technologies. The methodology can be used in many other applications in all kinds of process industries.

Abstract:
On 25 September 1992 the Department of Transport (DoT) issued a press notice stating that it would not be commissioning any new grouted duct post-tensioned bridges in England. The decision was taken due to fears that existing grouted duct post-tensioned concrete bridges were badly corroded and could be in a state of imminent collapse. The press notice also announced that existing grouted duct post-tensioned bridges were to undergo detailed inspection. Non-destructive techniques needed to be developed to allow detailed investigation of these structures. The results of these investigations had to be accurate to a high level of confidence as decisions on repair, renovation or destruction would be made on the findings of the investigation. This thesis will give the reasons for the DoT's decision followed by an overview of possible non-destructive techniques available at the time of issue. The main body of work carried out investigates the use of the Sonic Impact-Echo method of non-destructive testing. This involves the development of suitable testing equipment and preliminary laboratory and field investigation. Detailed numerical simulations were carried out using the Finite Element Method in order to quantify the probable limits of the Sonic Impact-Echo method. Final laboratory investigations were carried out on a model with known defects. Detailed field testing was carried out on test beams manufactured by the Transport Research Laboratory in Crowthorne and by TBV Stanger at Elstree.
