This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical application of three different processing methods for impact-echo test data?the classical impact-echo method, the peak frequency map, and the 4D spectrum technique?is performed and analyzed in this study. For comparative evaluation, a concrete slab with simulated delaminations and voids was cast and employed. Two conventional methods, the impact-echo and peak frequency map, are used to determine the relative performance of the 4D spectrum technique, in which the impact-echo data are presented as 4D maps representing x, y, the frequency, and the frequency amplitude for the tested area. For verification, the 4D spectrum technique and the other two methods were applied to three artificial defects at the depth of rebar in the designated concrete slab. The results obtained from comparing the three processing methods show that although three methods are comparable, the 4D spectrum technique is more effective and accurate for the detection of shallow defects in the slab.

Download or read book Nondestructive Testing Methods and New Applications written by Mohammad Omar and published by BoD – Books on Demand. This book was released on 2012-03-02 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive testing enables scientists and engineers to evaluate the integrity of their structures and the properties of their materials or components non-intrusively, and in some instances in real-time fashion. Applying the Nondestructive techniques and modalities offers valuable savings and guarantees the quality of engineered systems and products. This technology can be employed through different modalities that include contact methods such as ultrasonic, eddy current, magnetic particles, and liquid penetrant, in addition to contact-less methods such as in thermography, radiography, and shearography. This book seeks to introduce some of the Nondestructive testing methods from its theoretical fundamentals to its specific applications. Additionally, the text contains several novel implementations of such techniques in different fields, including the assessment of civil structures (concrete) to its application in medicine.
Download or read book Structural Health Monitoring Damage Detection Systems for Aerospace written by Markus G. R. Sause and published by Springer Nature. This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.

Available in PDF, EPUB and Kindle. Book excerpt: This book was proposed and organized as a means to present recent developments in the field of nondestructive testing of materials in civil engineering. For this reason, the articles highlighted in this editorial relate to different aspects of nondestructive testing of different materials in civil engineering—from building materials to building structures. The current trend in the development of nondestructive testing of materials in civil engineering is mainly concerned with the detection of flaws and defects in concrete elements and structures, and acoustic methods predominate in this field. As in medicine, the trend is towards designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. From this point of view, interesting results with significance for building practices have been obtained
