Download or read book Validation of Numerical Simulations by 3D Scanning written by Samir Lemeš and published by LAP LAMBERT Academic Publishing. This book was released on 2012-02-15 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Validation is the subjective process that determines the accuracy with which the mathematical model describes the actual physical phenomenon. This research was conducted in order to validate the use of finite element analysis for springback compensation in 3D scanning of sheet metal objects. The measurement uncertainty analysis was used to compare the digitized 3D model of deformed sheet metal product with the 3D model obtained by simulated deformation. The influence factors onto 3D scanning and numerical simulation processes are identified and analyzed. It is shown that major contribution to measurement uncertainty comes from scanning method and deviations of parts due to manufacturing technology. The analysis results showed that numerical methods, such as finite element method, can successfully be used in computer-aided quality control and automated inspection of manufactured parts.

Download or read book Guided Waves in Structures for SHM written by Wieslaw Ostachowicz and published by John Wiley & Sons. This book was released on 2011-12-30 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding and analysing the complex phenomena related to elastic wave propagation has been the subject of intense research for many years and has enabled application in numerous fields of technology, including structural health monitoring (SHM). In the course of the rapid advancement of diagnostic methods utilising elastic wave propagation, it has become clear that existing methods of elastic wave modeling and analysis are not always very useful; developing numerical methods aimed at modeling and analysing these phenomena has become a necessity. Furthermore, any methods developed need to be verified experimentally, which has become achievable with the advancement of measurement methods utilising laser vibrometry. Guided Waves in Structures for SHM reports on the simulation, analysis and experimental investigation related propagation of elastic waves in isotropic or laminated structures. The full spectrum of theoretical and practical issues associated with propagation of elastic waves is presented and discussed in this one study. Key features: Covers both numerical and experimental aspects of modeling, analysis and measurement of elastic wave propagation in structural elements formed from isotropic or composite materials Comprehensively discusses the application of the Spectral Finite Element Method for modelling and analysing elastic wave propagation in diverse structural elements Presents results of experimental measurements employing advanced laser technologies, validating the quality and correctness of the developed numerical models Accompanying website (www.wiley.com/go/ostachowicz) contains demonstration versions of commercial software developed by the authors for modelling and analyzing elastic wave propagation using the Spectral Finite Element Method Guided Waves in Structures for SHM provides a state of the art resource for researchers and graduate students in structural health monitoring, signal processing and structural dynamics. This book should also provide a useful reference for practising engineers within structural health monitoring and non-destructive testing.

Download or read book Neotectonics and Quaternary Fault reactivation in Europe s Intraplate Lithosphere written by Sierd Cloetingh and published by Elsevier Science & Technology. This book was released on 2005 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The EU funded interdisciplinary Environmental Tectonics research program ENTEC has led to new insights into the strength distribution of Europe's intraplate lithosphere, and its relationship with the localization of intraplate deformation and associated vertical motions. Pronounced lateral variations in Europe's intraplate strength occur, as a result of recent thermal perturbation in the underlying mantle and inherited inhomogeneity in lithospheric structures, as a result of Europe's polyphase pre-Quaternary evolution. Results are presented from quantitative subsidence analysis studies, and constraints by geothermochronology, pointing to pronounced acceleration in differential vertical motions and associated topography development in intraplate Europe. These results demonstrate the vulnerability of Europe's lithosphere to neotectonic activity documented by detailed studies in the three natural laboratories of the ENTEC program: (1) the Lower Rhine Graben (LRG), (2) the Upper Rhine Graben (URG), and (3) the Vienna Basin (VB).
