Published 2005Staff ViewISSN: 1551-2916Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsPhysicsNotes: The capacitance of the Na2O–SiO2 glass was measured in situ during heat treatment at various frequencies, 20, 100, 1, 3, 10, and 30 kHz. It was found that the capacitance of the glass abruptly decreases after a certain duration. The glass was quenched at this stage. It was confirmed by the X-ray diffraction and transmission electron microscopy that this decrease of capacitance was associated with the formation of crystallites in the glass matrix. The size of crystallites was observed to be in the range of about 10 nm.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4862Keywords: Holography ; overlapping debonds ; nondestructive testingSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMathematicsNotes: Abstract Debonds in laminated plates, particularly those made of glassfiber-reinforced plastics, can be readily detected using double-exposure holography when an incremental vacuum pressure is applied between exposures. With the aid of a model developed in this paper, a method is presented for inspecting a laminated plate containing flaws in the form of two identical circular debonds which are fully overlapped. Two holograms are taken, one on each side of the plate; the anomalous fringe patterns enable not only the detection of the presence of fully-overlapping debonds, but also an estimation of their size and depths. The technique can be applied during the shop testing, i.e., for the detection of defects occurring during the manufacturing of composite laminates, because both sides of the laminate must be inspected. This capability contributes further to realizing the potential of holography in nondestructive testing and evaluation of components.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4862Keywords: Laser ; speckle interferometry ; shearography ; NDE ; metals ; compositesSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMathematicsNotes: Abstract This paper presents some examples of nondestructive flaw detection using an optical method based on speckle shearing interferometry called shearography. In the method, a structure under study is illuminated by laser and imaged by a special image-shearing camera. After suitable processing, a fringe pattern which represents loci of surface displacement derivatives, i.e., strains, is observed in the image. Since defects in structures usually induce strain concentrations around them and since strain concentrations usually cause perturbations on the surface of structures, shearography reveals defects from anomalies in the recorded fringe pattern. In this work, the technique has been applied to the nondestructive detection of various flaws in plain and welded pipes, composite plates, and other engineering components. A simple model was also developed for the estimation of the depth of disbonds in glassfiber reinforced plastic sheets. Results obtained are good and demonstrate the usefulness of the method as a complement to other conventional NDT techniques.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4862Keywords: Shearography ; arbitrarily-oriented disbonds ; shape of disbonds ; size of disbonds ; depth of disbondsSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMathematicsNotes: Abstract Disbonds in a laminated plate are readily revealed from anomalies in the fringe pattern of a shearogram. The shearographic fringes represent loci of constant displacement derivatives of the deformed surface of the plate when subjected to a load increment such as vacuum stressing. In this investigation, a simple method is developed for easy estimation of the size and depth of arbitrarily-oriented square disbonds in laminated plates from a shearogram. The theory and experimental method presented may also be extended to the assessment of disbonds of arbitrary shapes.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1434-4726Keywords: Key words Cholesteatoma ; Children ; TympanoplastySource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract We studied retrospectively 28 cases of cholesteatoma in children whose ages were 3 to 13 years old. All had undergone surgery between 1989 and 1995. The intact canal wall technique was the predominant method used in the initial operation, with long term goals of an anatomically normal and infection-free ear. Cholesteatoma was found postoperatively in 15 cases and was considered to be residual in 6 cases and recurrent in 9. The residual cholesteatoma was relatively uncommon and usually removable in an exploratory second operation. Our findings showed that the intact canal wall technique was the best initial operation if two-stage surgery was planned. Avoidance of a retraction pocket, which tends to progress to a recurrent cholesteatoma, is important to successful treatment.Type of Medium: Electronic ResourceURL: -

ISSN: 1741-2765Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The propagation of a flexural wave generated by transverse point impact on a beam between clamped supports is observed using pulsed-laser shearography—the rapid double exposure of holographic film to a laser-illuminated object at different instants of its deformation. Sequential images are captured via a camera which has a thin, wedge-shaped prism placed in front of half its lens. This prism produces another image which is sheared in the direction of the wedge, with a net result that two images—sheared with respect to each other—are recorded by the camera. When the structure is deformed and a second exposure is superimposed on the first, a fringe pattern is produced; this becomes visible when observed via high-pass optical Fourier filtering. The fringes represent loci of constant out-of-plane displacement derivatives with respect to the direction of image shear. These are integrated to yield the instantaneous out-of-plane displacement induced by the flexural wave. Adjustment of the delay between the first and second laser pulses produces sequential displacement data on the propagating wave. This is compared with theoretical results based on Timoshenko beam analysis employing the method of characteristics to compute displacement values. The experimental data compare favorably with theoretical predictions, substantiating the use of sheariographic techniques for stress-wave studies.Type of Medium: Electronic ResourceURL:
