摘要:We study the procedures used to increase the informativity of the impedance method of nondestructive testing. The statistical methods of processing informative signals with an aim to improve the reliability of nondestructive testing are analyzed. For the statistical processing of...

摘要:Ultrasound imaging systems (UIS) are essential tools in nondestructive testing (NDT). In general, the quality of images depends on two factors: system hardware features and image reconstruction algorithms. This paper presents a new image reconstruction algorithm for ultrasonic ...

摘要:... It is difficult to carry out online nondestructive testing (NDT) of FSWR in the process of manufacturing. In this paper we present a novel MFL method for FSWR NDT in a strong electromagnetic interference environment. We use a three-dimensional finite element method (FEM) to a...

摘要:... We implemented the proposed algorithm and performed a systematic experiment by using a 450-kV industrial x-ray inspection system to demonstrate its viability for nondestructive testing. Our results indicated that the structure of the examined object was much more clearly vi...

摘要:... We implemented the proposed algorithm and performed a systematic experiment to demonstrate its viability for image deblurring in x-ray nondestructive testing. We obtained x-ray images of several selected electronic components at an x-ray tube condition of 80 kV p and 1.25 mAs...

摘要:Theoretical aspects of applying Lamb waves to nondestructive testing of layered anisotropic media are considered. Propagation of Lamb waves is analyzed using a six-dimensional complex Cauchy formalism that allows one to obtain a closed-form equation for determining the dispersion...

摘要:... Using the example of electrical responses from samples of heavy- and light-weight concretes and based on numerical modeling results, prospects are shown for using this phenomenon in nondestructive testing of heterogeneous nonmetallic materials that do not contain piezoelectri...

摘要:... Compliance of a nondestructive testing technique with its indicated purpose indicators, which may include numerical values of the certainty index achieved with the technique, is established during verification. Experimental research that is part of the verification procedu...

摘要:It is proposed that magnetic information parameters constructed from the parameters of the full magnetic hysteresis loop of steels be used for nondestructive testing of medium-carbon alloy steels. Analytic expressions for calculating the relative error in the determination of the...

摘要:... The proposed approach is particularly relevant when a three-dimensional formulation is adopted for nondestructive testing using infrared thermography. For such a formulation, heat flux density resulting from the external thermal stimulus is needed and must be determined to ac...
