Title: Formability Prediction Of Aluminum Sheet In Automotive Applications

Abstract

In the following paper, a full mechanical characterization of the AA6016 T4 aluminum alloy car body sheet DR100 is presented. A comprehensive experimental program was performed to identify and model the orthotopic elasto-plastic deformation behavior of the material and its fracture characteristics including criteria for localized necking, ductile fracture and shear fracture. The commercial software package MF GenYld + CrachFEM in combination with the explicit finite element code Ls-Dyna is used to validate the quality of the material model with experiments, namely, prediction of the FLD, deep drawing with a cross-shaped punch and finally, analysis of a simplified hemming process using a solid discretization of the problem. The focus is on the correct prediction of the limits of the material in such processes.

  • The frictional properties of interfaces are of interest in a broad range of applications. We have formulated a new plasticity model for interface friction and applied it to represent the frictional characteristics of A16111-T4 sheet against D2 tool steel for sheet forming applications.
  • The microstructure of both 5000 and 6000 series alloy sheet can be controlled to provide the properties required for particular automotive applications. The work-hardening 5000 series alloys, with between 3 and 6% Mg as the major alloying addition, are supplied to the automotive companies in the annealed temper and are characterized by a recrystallized grain structure which is influenced by the insoluble Fe-based intermetallics, dispersoids, and the work-hardening rate. The annealed strength and formability is strongly dependent upon grain size, Mg content, and, to a lesser extent, on crystallographic texture. The 6000 series alloys containing Cu, Mg, and Si aremore » somewhat more complicated to control, because of precipitation of the age-hardening phases during fabrication. It is necessary to control the processes of dispersoid and precipitate formation so as to obtain the desired strength, grain size, and crystallographic texture in the final sheet. These alloys also offer a low solution-treated strength for high formability, combined with rapid age hardening to a relatively high strength in the formed component during the paint bake cycle.« less
  • The formability in sheet metal forming processes is mainly conditioned by ductile fracture resulting from geometric instabilities due to necking and strain localization. The macroscopic collapse associated with ductile failure is a result of internal degradation described throughout metallographic observations by the nucleation, growth and coalescence of voids and micro-cracks. Damage influences and is influenced by plastic deformation and therefore these two dissipative phenomena should be coupled at the constitutive level. In this contribution, Lemaitre's ductile damage model is coupled with Hill's orthotropic plasticity criterion. The coupling between damaging and material behavior is accounted for within the framework of Continuummore » Damage Mechanics (CDM). The resulting constitutive equations are implemented in the Abaqus/Explicit code, for the prediction of fracture onset in sheet metal forming processes. The damage evolution law takes into account the important effect of micro-crack closure, which dramatically decreases the rate of damage growth under compressive paths.« less
  • A criterion for ductile fracture is applied to the formability prediction of an aluminum 2024 alloy sheet and its laminated composite sheets. Axisymmetric deep-drawing processes of the 2024 sheet and the laminates clad by mild steel sheets are simulated by the finite-element method. From the calculated distributions and histories of stress and strain, the fracture initiation site and the forming limit are predicted by means of the ductile fracture criterion. The predictions so obtained are compared with experimental observations. The results show that the fracture initiation in the 2024 sheet with no appearance of necking is successfully predicted by themore » present numerical approach. Furthermore, it is found that the formability of the 2024 sheet is improved by sandwiching it with the mild steel sheets.« less
  • Because of environmental concern and government pressure, automakers are exploring ways to increase the fuel economy of vehicles. Mass reduction can be achieved by substituting plastics, aluminum, or high-strength steel for ordinary grades of steel in the autobody. Estimates of fuel economy increases range from 3% to 7% for each 10% reduction in mass. The use of aluminum for mass reduction currently is receiving considerable attention. Cold-rolled steel, electrogalvanized steel (60 g/m{sup 2} coating), and three aluminum alloy sheet products (Al 2036, Al 5182, and Al 6111) were painted with a full automotive paint system. These materials were tested inmore » two laboratory cyclic corrosion test environments, GM9540P(B) and CCT-IV. Resistance to cosmetic corrosion was measured in terms of underfilm paint delamination on scribed, flat panels. Crevice corrosion resistance was determined in terms of pitting on lapped panels of like materials, and galvanic corrosion resistance was determined in terms of pitting on lapped panels of unlike materials. Cosmetic corrosion of the aluminum alloys was found to be much better than that of cold-rolled steel and slightly better than that of electrogalvanized steel. The CCT-IV test was found to be more severe than GM9540P(B) for cosmetic corrosion, but GM9540P(B) was more severe for galvanic corrosion. Galvanic current measurements indicated the difference was related to the salt solutions used in each test. The aluminum alloys were prone to crevice corrosion and to galvanic corrosion when coupled to steel. Results indicated that comparative evaluations of the corrosion resistance of these materials must take into account the possibility of crevice and galvanic effects.« less
