Title: A method of modeling the forming of anisotropic sheet
Inventor: WU PEI-DONG
IPC: B21D37/20
Filed: 1999-11-16
Granted: 2005-03-29
Abstract: A method of fabricating an article from a blank (12) of material (e.g., aluminum alloy sheet) having anisotropic deformation properties, with tooling (14) which has been designed by predicting flow and deformation of the blank (12) using an analysis which decouples the anisotropic deformation properties of the blank (12). The method calculates the response of a small amount of the blank (12) using crystal plasticity theory. The blank (12) can be represented as a mesh having a plurality of elements. A strain path is predicted for each element using finite element analysis (FEA), and a stress-strain curve is defined for each element by performing a material point simulator (MPS) calculation for each element using its respective strain path. A second FEA is then carried out on the elements using the respective stress-strain curve for each element. The stress-strain curve for each element may be defined by assigning to each element a curve which lies between an upper bound curve and a lower bound curve, using various methods.      The computational model requires much less CPU time compared to prior art methods.

Abstract: The multi-layer film structure having an inner sealing layer (36) which comprises metallocene resin, a core (38) which includes polypropylene copolymer and an outer layer (37) and wherein the multi-layer film structure has a thickness (X) within a range between about 50 and 70 microns (2.0 - 2.75 mil). By utilizing this thin film with specific properties the sealers may be operate d at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10.degree. C to 15.degree.C and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This result s in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength. The machine accomplishes better seals with less energy, requires less downtime for roll changes and maintenance and increase throughput.

Granted: 2011-03-22
Abstract: Cette invention concerne un procédé destiné à interdire ou a empêcher la corrosion des armatures en acier du béton grâce à la suppression des différences de potentiel de surface, ce qui assure une passivation totale de l'activité corrosive et crée dans l'acier un environnement qui empêche la corrosion. Ce procédé consiste éventuellement à mesure le potentiel de surface actif non uniforme dans l'acier en faisant passer un courant continu dans le béton et l'acier pour arrêter la corrosion grâce à l'établissement d'un potentiel de surface sensiblement uniforme sur les armatures d'acier. On limite et l'on règle le courant de manière à envoyer des doses prédéterminées d'énergie dans des zones destinées à être traitées. Il est possible de procéder à une étude sur la corrosion potentielle afin de déterminer les besoins d'énergie pour le cas considéré ou bien de disposer une électrode de référence en un point stratégique de la structure de béton. La quantité d'énergie qui passe dans le béton est suffisante pour créer une polarisation des armatures d'acier et établir des potentiels de surface sensiblement uniformes pour la totalité des armatures. L'invention concerne également le changement des conditions sur la surface de l'acier, avec le passage d'un potentiel de surface non uniforme à un potentiel de surface sensiblement uniforme.
