Download or read book Validation of Numerical Simulations by Digital Scanning of 3D Sheet Metal Objects written by Samir Lemeš and published by Univerza v Ljubljani, Fakulteta za strojništvo. This book was released on 2010-06-23 with total page 178 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 analysed. 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 Advances in Digital Image Correlation DIC written by Jean-Noël Périé and published by MDPI. This book was released on 2020-04-21 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital image correlation (DIC) has become the most popular full field measurement technique in experimental mechanics. It is a versatile and inexpensive measurement method that provides a large amount of experimental data. Because DIC takes advantage of a huge variety of image modalities, the technique allows covering a wide range of space and time scales. Stereo extends the scope of DIC to non-planar cases, which are more representative of industrial use cases. With the development of tomography, digital volume correlation now provides access to volumetric data, enabling the study of the inner behavior of materials and structures.However, the use of DIC data to quantitatively validate models or accurately identify a set of constitutive parameters remains challenging. One of the reasons lies in the compromises between measurement resolution and spatial resolution. Second, the question of the boundary conditions is still open. Another reason is that the measured displacements are not directly comparable with usual simulations. Finally, the use of full field data leads to new computational challenges.

This book was released on 2005-08-19 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Numisheet Conferences occur once every three years, alternating in location between North America, Europe and Asia. The conference attracts international participation from the metal forming industry and university professors interested in sheet metal forming technology, with a strong emphasis on forming simulation. Although the conference is dominated by the automotive industry, the conference has a wider appeal, drawing contributions from the aircraft and canning industries as well. The Numisheet Conference Proceedings include the latest developments in metal forming technology, which is a rapidly growing and challenging opportunity for application of science to industry. The developments are described in over 125 papers included in Part A of the proceedings. In addition, this volume includes the Numisheet Keynote Program which focused on cutting areas of technology, and was presented by selected leading scientists in the field of metal forming. One of the hallmarks of the conference is the Numisheet Benchmark Study, which is a set of three blind tests prepared one year prior to the conference. Participants are invited to submit their predictions of how selected types of sheet metal will deform under large plastic deformation during the manufacture of actual automotive products and laboratory test specimens. The complete specifications and results of this blind test are described in Part B of the proceedings.

Available in PDF, EPUB and Kindle. Book excerpt: The plastic forming of metallic materials is the most efficient and an important manufacturing technology in today's industry. Lightweight materials, such as titanium alloys, aluminum alloys, and ultra-high-strength steels, are used extensively in the automotive, aerospace, transportation, and construction industries, leading to increased demand for advanced innovative forming technologies. Today, numeric simulations are highly focused and provide a better understanding of the innovative forming processes. Computational methods and numerical analysis coupled with the modelling of the structural evolution allow us to reduce time costs and eliminate experimental tests. The subjects of research articles published in this nook are multidisciplinary, including friction and lubrication in sheet metal forming, hot strip rolling and tandem strip rolling, application of numeric methods to simulate metal forming processes, development of new creep performance materials, the single point incremental forming process, and the fatigue fracture characteristics of Alclad 7075-T6 aluminum alloy sheets joined by refill friction stir spot welding. Review articles summarize the approaches on the innovative numerical algorithms, experimental methods, and theoretical contributions that have recently been proposed for sheet metal forming by researchers and business research centers.
