Numerical simulations of the incompressible Euler equations are performed using the Taylor-Green vortex initial conditions and resolutions up to 4096^{3}. The results are analyzed in terms of the classical analyticity-strip method and Beale, Kato, and Majda (BKM) theorem. A well-resolved acceleration of the time decay of the width of the analyticity strip δ(t) is observed at the highest resolut...

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work...

The alternate strip-based iterative substructuring algorithms are preconditioning techniques for the discrete systems which arise from the finite element approximation of symmetric elliptic boundary value problems. The algorithms presented in this paper may be viewed as simple, direct extensions of the two disjoint subdomains case to the multiple domains decomposition with interior cross-points...

Micro flexible rolling aims to fabricate submillimeter thick strips with varying thickness profile, where the surface quality of products is mainly determined by initial workpiece surface roughness and subsequent surface asperity flattening process, which is affected by process parameters during rolling. This paper shows a 3D finite element model for flexible rolling of a 250 μm thick workpiece...

The present article deals with a composite casting process that allows to produce bilayer AlSn6-Al strips based on the technique of horizontal continuous casting. In the first part experimental investigations on the production of a single layer AlSn6 strip are described. Afterwards essential results of basic compound casting trials using simple test specimen are presented to define the thermal ...

In order to get a more safety and economic foundation, finite element method was performed for piled mat cap strip by the software of STAAD. Through analysis, plate distribution region bending moment shear stress were researched; meanwhile, considering compatibility deformation plate, how chose design value researched. The result showed that: single is not representative, average 9 plates (3x3 ...

Axially moving strips are frequently encountered in industry for various applications. On the one hand, accurate models of transverse displacements of strips are desired for plant design and safety or reliability reasons. On the other hand, the models may serve as a basis for model-based controller and observer design. For the latter also, the complexity of the models should be as low as possib...

Abstract This study investigates the mechanical properties and microstructural characteristics of explosion-welded Al/Cu two-layer strips during ECAR process using finite element simulations experiments. Furthermore, strip was examined with various configurations to determine effects die angle friction coefficient on distributions effective strain stress. In addition, experimental computational...
