Повний текст джерелаBuildings represent a large share in terms of energy consumption, such as 35% in the member countries of IEA (2010) and 39.8% in U.S. (2015). Climate controlling (space heating and space cooling) occupies more than half of the consumption. While this consumption can be reduced by improving the building energy efficiency, in which the thermal performance of building envelope plays a critical role. Therefore, the thermal diagnosis of building envelope is of great important, for example, in the case of new building accreditation, retrofitting energy efficiency of old building and the building resale and renting. However, very few diagnostic methods exist for the characterization of thick walls. The present measurement standards that based on steady state heat transfer regime need a long time (several days). The classical transient technologies, such as flash method, are difficult to implement on the walls because of the large thickness of walls and the complex conditions in situ. This thesis aims to explore innovative methodologies for thermal quantitative diagnosis of building envelope. Two experimental cases were carried out: one is in laboratory (IFSTTAR, Nantes) and the other is in situ (IUT, Bordeaux). Different sensors and instruments were studied to measure the wall heat flux and surface temperature, and provided some guidelines for the choice of sensors and data processing protocols as well. Using these measured data, three estimation approaches were proposed to estimate the thermal parameters of the multilayer thick wall: pulse response curve method, step response curve method and inverse method, which can be applied for different diagnostic situations. In addition, an innovative NDE (non-destructive evaluation) method using terahertz (THz) radiation was also investigated. Measurements were carried out in I2M laboratory to characterize the absorption coefficient of standard building materials (insulation, plaster, concrete, wood ...). This THz method can be combined with a previous thermal method to provide some complementary information

The dissertation is devoted to the question of immunity to interference improvement in the thermal non-destructive testing of multilayered honeycomb constructions and pipelines, both by the monitoring mode selection with the criterion of maximum signal-to-interference ratio, and by the further computer processing of obtained experimental data. Thermophysical models of multilayered honeycomb constructions are proposed. The software package "TermoPro_TFH_Statistic" was worked out and number of experiments at the thermal flaw detection modes selection were performed on its basis. A number of full-size and laboratory-scale experiments were conducted to investigate the interference effect on thermal non-destructive testing. A number of filters have been worked out, as well as the sequence of their use to significantly reduce the interference level during the thermal flaw detection. Due to this, the sensitivity of thermal defectoscopy to detection of defects of the "non-adhesive" type in honeycomb structures increased – the size of the threshold defect was decreased from 6mm to 3mm, and the reliability of their detection increased by 17-20%.

Повний текст джерелаThe composite materials are widely used in industry because of their high mechanical resistance and low density. The diversity of composite materials application fields gives rise to a large variety of solicitation and damage conditions. For this reason, the evaluation of their properties and their health monitoring are of great industrial interest. In this work, a new method of evaluation and non-destructive testing named sonothermography is explored. This method is based on the analysis of thermal fields induced by ultrasonic waves in absorbent materials such as composites. Two additional applications are studied: the evaluation of the thermal properties of the material and the non-destructive testing of structures by infrared thermography. In this framework, the direct problem of sonothermography is solved numerically using a model based on the finite element method. This model allows to simulate the thermal field induced by the propagation of ultrasonic waves in absorbent material whose properties are known. The simulations carried out show the applicability of the sonothermography for the detection of defects. An innovative approach for thermal characterization is also developed. This approach based on the weak formulation of the heat conduction equation allows a robust estimate of the thermal diffusivity of the material from the thermal field induced by ultrasonic waves. Experimental results are presented for thin plates

Повний текст джерелаThe aim of this work is the detection of open and subjacent defects in metallic materials using laser-material interaction coupled with infrared thermography. This process is a possible alternative for magnetic particles testing and dye penetrant testing in the field of non-destructive testing. This work is divided into three main parties. At first, we have been interested in the characterization of optical and thermophysical properties of materials we used, in order to have good boundary conditions and also for the needs of temperatures fields measurements for validation. The second part concern the development of a numerical simulation model with two step approach: the first involves modelling temperature field with finite element method and the second details the infrared camera modelling. Innovative solutions were used to obtain model which integrates all parameters, with low time calculation. After validated temperature field, this model allows us to look for the process optimal parameters through numerical experimental designs

Повний текст джерелаThis thesis focuses on the use of infrared thermography as a tool for non destructive testing ofbuildings. Mainly, the application is on civil engineering projects.The first part includes identifying the parameters that can affect this in situ technique. Thisparticularly deals with the infrared thermography capacity to detect intrinsic property variations, anddelamination detection. Combination of experiments on concrete slabs and numerical simulationsare used. In a first step, a study on the capacity of thermography to detect porosity and watercontent variation was conducted. In a second step a study on the thresholds for detectingdelaminations based on exposure conditions is carried out. As an outcome, the threshold that hasbeen detected corresponds to a ratio of 2 between the lateral extension of the defect and its depthto direct sunlight; while a ratio of 3,3 if it is exposed to air temperature variations. This studysuggests that a time monitoring combined with the study of the evolution of temporal temperaturegradients can improve the detection limits. Finally, an original study showed the predominance ofthe influence of bridging on the depth of delamination.The second part tackles the works carried out during the ANR project SENSO. Results fromdifferent non destructive tools were coupled for the purpose of improving diagnosis in the assetmanagement
Deng, Xiaodong. "Nondestructive evaluation of thermal sprayed coating by acoustic microscopy and Eddy current testing." Thesis, Lyon, INSA, 2014. http://www.theses.fr/2014ISAL0030/document.
Повний текст джерелаIn the current work, we investigate the nondestructive evaluation of a thermal sprayed coating (Hastelloy C22 Ni-based alloy) on substrate (type 304 austenitic stainless steel) using acoustic microscopy and ECT method. Two models were built for the evaluation of this kind of material: one is for acoustic V(z) measurement and the other is for swept eddy current measurement. The implementation of these two models is used for the evaluation and properties measurement of the thermal sprayed coatings, such as elastic properties, electromagnetic properties. In particular, the main achievements and results are as follows: 1. Acoustic wave propagation in an anisotropic multilayered medium was investigated. The formula for calculating the reflection and transmission coefficients of the multilayered medium on or without a substrate were derived, which is necessary for the modeling of acoustic V(z) measurement of the thermal sprayed coating on substrate. 2. A model was built for the acoustic V(z) measurement of the thermal sprayed coatings on substrate, which can deal with anisotropic multilayered media. Specifically, we used a model of multilayered coatings with graded properties on substrate to calculate the acoustic reflection coefficient of our sample. Treating the thermal sprayed coating, deposited on a 304 steel substrate, as FGMs, we evaluated the coating thickness and the Young’s modulus evolution along the depth of the coating. 3. A model was built for the swept eddy current measurement of the thermal sprayed coatings. Since before the spraying process, the surface of the substrate is usually shot-peened (SP), the coated material is considered as a three-layer medium. The coating thickness and electromagnetic properties of each of the 3 layers were determined by an effective reverse process. 4. The thermal sprayed coated material after exposure in different conditions, i.e., as-received, heat-treated in air and heat-treated in SO2 environment, and after different exposure time was evaluated by the integrity of acoustic microscopy and ECT method. The coating thickness and the electromagnetic properties of the coated material under different conditions were measured

Повний текст джерелаIn today’s competitive market, the quality control is vital in steelmaking industry where high quality product must pair with cost reduction. This control can be described as a system used for verifying and maintaining a desired level of quality. It implies careful inspection and corrective action if needed. The inspection can be performed with several Non-Destructive Testing (NDT) techniques to detect defects. Since the detection at the earliest possible stage is vital for the reduction of the quality cost, the ultrasonic systems have been used at pickling stage to detect internal defects without slowing down the production paces. However, there is still a need of a sensitive NDT technique to detect near subsurface defects which may turn into surface defects at downstream stages or even worse, at the customers during forming.Amongst the common NDT techniques, Active Infrared Thermography (AIRT) was identified as having a great potential for the detection of near surface internal defects. As an attractive NDT technique, AIRT has remarkable: it is contactless, relatively fast and versatile. Its principle is relatively simple: it consists in heating the sample and monitoring the surface response with an Infrared (IR) camera. The presence of any subsurface defect appears as specific thermal patterns in the recorded thermal sequence. Despite being an attractive technique, AIRT is not deployed yet to detect subsurface defects in steel strip at pickling stage on an industrial production line which is the innovative part of this thesis.The work provided in the thesis investigates the theoretical and experimental limits of AIRT for the detection of subsurface defects in steel samples. First, the investigation led to the development of laboratory tools capable of detecting near subsurface defects in static as well as moving samples. These developments are supported by 3D simulations which allowed evaluating the potential of the technique; gaining comprehensive knowledge; getting guidance for and/or optimize experimental designs. Then, the knowledge developed in laboratory has allowed outlining that the technique can be implemented directly in production line; especially at pickling stage where the strip travels at typically 5 m/s. Therefore, an inspection system was built and successfully implemented for the inspection of a reduced width of the moving strip in industrial environment. The thesis presents encouraging results and some keys identified points that should be considered for the design of full-integrated industrial AIRT inspection system
