Sheet Formability

This paper has introduced the finite element analysis (FEA) into the ergonomic design to evaluate the human feelings numerically and objectively, and then into the optimization design of beverage containers considering human factors. In the design of the end of can (the lid of can), experiments and the FEA of indenting vertically the fingertip pulp by a probe and the tab of end have been done to observe force responses and to study feelings in the fingertip. A numerical simulation of finger lifting the tab for opening the can has also been performed, and discomfort in the fingertip has been evaluated numerically to present the finger-accessibility of the tab. The comparison of finger-accessibility between two kinds of tab ring shape designs showed that the tab that may have a larger contact area with the finger is better. In the design of beverage bottles served hot drinks, the FEA of tactile sensation of heat has been performed to evaluate numerically the touch feeling of the finger when holding the hot bottle. The numerical simulations of embossing process have also been performed to evaluate the formability of various rib-shape designs. The optimum design has then been done considering the hot touch feeling as well as the metal sheet formability.

The role of rare earth addition on the microstructure and texture during recrystallization of cold rolled sheets is investigated by a comparative study of pure Mg, Mg-3Y and Mg1.5Nd sheets. In pure Mg, nucleation occurs mainly at shear bands which results in a texture weakening. The basal-type texture re-strengthens rapidly during grain growth of the pure Mg sheet. In contrast, in the Mg-RE alloys the weaker texture formed during early recrystallization strage is retained during further annealing due to retarded grain growth. Uni-axial tensile and Erichsen tests show that ductility and sheet formability are significantly improved by addition of rare earth elements.

Forming Limit Curves

Sheet metal forming experiments have been carried out on AZ31 and ZE10 sheets produced by rolling conventionally DC cast slabs as well as twin roll cast (TRC) strips. Nakajima tests were performed on the various sheet materials over the temperature range from RT to 200 °C using Hasek type samples of specified geometries to generate various strain paths. The strain path data were used to derive the forming limit curves as plotted in forming limit diagrams for the two alloys. The temperature dependence of the sheet formability is discussed in terms of the operating deformation mechanisms and the roles of alloy composition, initial texture and processing history.
