265、报告题目:非破坏性测试中分数阶导数的使用
Title of the report: The Use of Fractional Order Derivatives in Non-Destructive Testing
报告人:理查德.西科拉
Reporter: Ryszard Sikora
单位:西波美拉尼亚的理工大学
UnitWest Pomeranian University ofTechnology
摘要Abstract:
The fractional order derivatives and integrals are known since 1695 yearwhen Leibniz and L’Hospital initiated the discussion aimed at calculus based onfractional order derivatives and integrals. For a long time, areas forpractical applications of this calculus have not been found. The lack ofapplications has been caused by serious difficulties referring to possibilitiesof clear physical and technical interpretation of fractional calculusformulae.   Nevertheless, there are noobstacles in use of this calculus in more or less “virtual” areas, such as, forexample, control theory, where there exist many degrees of freedom inmathematical creation of control laws. The number of papers using fractional order derivatives refer toelectrical engineering. Unfortunately, substantial number of mentioned above publicationscontain serious errors.  There are manyformulations defining the fractional order integrals and derivatives. Thus, onehas to overcome problem of choice of the right formulation for problem beingsolved. It should be mentioned that the following three among them are commonlyused, i.e. Gruinvald-Letnikov, Caputo, Riemann-Liouville [1]. After selectingthe correct formulation, the calculations have to be performed.  On the beginning one has to define thelinear, fractional order elements of electric circuit   used in non-destructive testing, forexample, these can be elements applied for construction of the transducerdetecting flaws on the basis of eddy-current technique.  These elements are not expressed with units:Ohm, Henr and Farad. Their respective physical units depend on the order ofderivatives. To avoid inconsistencies referring to Kirchhoff's law the“dedicated” coefficients are introduced to formula describing each circuitelement:  . By means of above adjustmentof physical units the Kirchhoff’s law for serial RLC circuit will be kept. Thenfractional order differential equations describing circuits are treatedmathematically. As the essence of the proposed approach one can treat creationof circuits with desired frequency characteristics. The formulae will betreated as theoretical standards for designing of innovative diagnostic systemsbased on the eddy-current technique. Thus, the obtained systems can be treatedas filters which approximate the desired frequency characteristics. Theproposed systems enable identification of the defect parameters as well. Thefull paper will contain the necessary elements of theory of the fractionalorder calculus as well as theory of eddy currents method using fractional orderderivatives of time. The selected examples will be also provided.  The proposed method can be used in case ofother testing methods, those described by means of differential equations (e.g.ultrasonic testing and others).

Title of the report: Evaluation of Degradation of Structural Materials by Magnetic IncrementalPermeability Method
报告人:上野本
Reporter: T. Uchimoto
单位:东北大学工学研究科
UnitGraduate School of Engineering,Tohoku University
摘要Abstract:
Magnetic techniques are practically used for evaluation of variousdegradations in steel components such as plastic deformation, residual stressand creep damage, and so on. However, most magnetic techniques are influencedby electromagnetic noises. Incremental magnetic permeability method measurescoil impedance during the magnetization that is equivalent to incrementalpermeability. It has an advantage of less noise-sensitive feature, because ofnarrow band filtering in measuring impedance. In this talk, some applicationsof incremental permeability method are introduced: plastic deformation of carbonsteels, and microstructure change of high Cr ferritic steels by creepdegradation. Incremental permeability as function of applied field changesaccording to microstructure change. In addition, trajectory of impedance in acomplex plain shows characteristic behaviors. These phenomena are discussedthrough the apparent permeability and conductivity reconstructed from theimpedance change.

Title of the report: Inspection and monitoring of bond line defects in composite structuresusing ultrasonic feature guided waves
报告人:范铮博士
Reporter: Dr. Fan Zheng
单位: 新加坡南洋理工大学
UnitNanyang Technological University
摘要Abstract:
Adhesivebonding is widely used in aerospace composite structures, being the most commonmeans to fix skins to reinforcing elements, such as spars and stiffeners. Acontinuous well-cured bond can offer uniform stresses, good joint strength, andimproved fatigue and impact resistance, and is therefore crucial to theperformance of the entire structure. This talk presents a novel technology touse feature guided waves (FGW) for rapid screening of the bond-line between astiffener and a carbon-fiber-reinforced-polymer (CFRP) composite panel. SuchFGW is capable of concentrating the energy along the stiffener and bond-line,with little energy leaking into the plate. Semi-Analytical Finite Element(SAFE) method is applied to understand the modal properties of FGWs that existin the structure, using both the homogeneous and the heterogeneous model forthe composite panel. Promising modes with little dispersion and littleattenuation are identified from the modal analysis. Both 3D Finite Element (FE)simulations and experiments are performed to study the interaction of theselected FGW mode with defects in the adhesive bond, and the results showexcellent agreement. The reflection behavior and the wave-defect resonancephenomenon are investigated, which demonstrate the capability of the FGW forthe bond line inspection. A new structural health monitoring (SHM) techniquebased on a synthetically focusing method using a sparse array of sensors isalso presented.

摘要Abstract:
With the demands of lightweight vehicles, the lasertailor-welded blank is gradually becoming an essential part in the automotiveindustry. The quality of all welds must be evaluated after the welding processto avoid breaks after the blank stamping and during the vehicle life. There areseveral inspection methods for Tailor Welded Blanks, but only an ultrasonicsystem is capable of detecting internal defects at high speed in an industrialenvironment. This article describes the ultrasonic system based on EMATtechnology for Laser Weld inspection, in which guided waves are used to inspectthe thin plates. The excitation of sound waves occurs on the surface of the materialrather than in the probe. For this reason, EMAT has the benefit of no couplant,non contact, feasible for low or high temperature and easy to integrate withautomation system.

Title of the report: Development ofElectromagnetic nondestructive testing for inspecting mechanical lap joint ofhigh-temperature superconducting tapes

摘要Abstract:
To facilitate construction andmaintenance of nuclear fusion reactors, a remountable (demountable)high-temperature superconducting magnet was proposed. The magnet is assembledfrom several segments with mechanical joints. The electrical resistance ofjoint at cryogenic temperature (joint resistance) has great influence on theperformance of the magnet, a nondestructive testing technique at roomtemperature is highly demanded to predict joint resistance.  In this study, we focused on electricalcharacteristics of the joint to develop an electromagnetic NDT technique forinspecting the joint. To identify the factors relating to the joint resistanceand the correlation between the electrical characteristics, we observed crosssections of the joint using X-ray CT scan and measured the electricalresistance and impedance of the joint. We found a small air gap existing in thejoint that could possibly be the cause for increment in joint resistance,though we could not evaluate the degree of influence of such gap over measuredelectrical resistance and impedance result. We analyzed the causes by numericalmodels, and found arranging the current perpendicular to the joint surface iseffective for inspecting the joint. Then we used numerical models to evaluatethe feasibility of applying the direct measurement and eddy current testing forinspection, the result showed the possibility of detecting particular air cap,optimization of the measurement condition is required.

摘要Abstract:
Some safety critical objects, suchas the rail track, oil pipeline, etc. must be inspected regularly. The shorterinspection period, the higher cost will be. The longer inspection period, themore possible safety risk will be.  Thequestion is how often the inspection will be carried out, which have a minimumsafety risk and less costs on inspection? This paper employed the Big Data (BD)analysis technique, and proposed a Big Data Analysis Enabled NDT systemframework to resolve the issue.
