“…Han et al [89] studied the heat transfer process of conventional clinching of magnesium alloy sheets using DFORM-3D®. They improved the dieless clinching of magnesium alloy sheets with the theory of TRIZ theory to reduce the preheating time [90]. The researchers found that the preheating time of clinching process with the new counter die can be reduced to 1 s, and the clinching process is efficient and reliable for joining the magnesium alloy sheets.…”

“…The detailed forming processes are generally divided into the following steps: the initial preparation phase, the pre-heating phase, the star formation of early phase, the formation of interlocking phase and the maintaining pressure phase. As for some requirements of high flatness, it will be added the phase for sustained pressure [7].…”

The clinching process of magnesium alloys has a great potential of being high efficient joining method, but it is restricted by the limited formability of magnesium alloys at room temperature. To form acceptable joints without cracking, it is usually required to heat the parts to about 220°C. However, the pre-heating times of traditional forming method is more than 3 to 6 seconds, the application of clinching for magnesium alloys is restricted by the over long periods of heating time. A new joining process with a contoured die is introduced to offer great benefits, especially in pre-heating time. Then the heat transfer process is simulated with DEFORM-3D software. The results show that the pre-heating time reduced to less than 1 second. Thus it is efficient and reliable in joining of magnesium alloys parts.

“…Therefore, the light-weight design of the large scaled stretch-forming die with the structural optimization methods is necessarily important. Currently, most of the existing works on the stretch-forming are concentrated on the numerical simulation of different kinds of forming process to improve the forming precision [1,2].…”

The purpose of this paper is to use the topology optimization method to solve the light-weight design problem of large aircraft skin stretch-forming die. The platform of ABAQUS is firstly used for numerical simulation of skin stretch-forming. And the surface load conditions are therefore obtained. The topology optimization is carried out accordingly to maximize the structural stiffness with the material properties and the boundary conditions properly defined. Referring to the obtained topology design, the optimal structure is reconstructed and then evaluated by the non-linear numerical simulation of stretch-forming. Compared with the traditional design, the numerical results have shown that the topology design can improve the stiffness and strength of the stretch-forming die significantly.
