The friction factor between 6061 aluminum alloy and die material (SKD61) are determined at different temperatures by using ring compression test which are carried out on a material testing machine. Mechanical properties and fiction factor are then applied to the finite element analysis of the wheel forging for different elevated temperature. Maximum forging load, effective stress and temperature distribution are determined of the wheel forging, using the finie element analysis. Finally, the wheel parts are formed by the forging machine under the conditions using finite element analysis.

The feasibility of forging of AL-1050 alloy of cylindrical heatsink under warm conditions is demonstrated in the present work. The stress-strain curves and friction factor play an important role in the cylindrical heatsink forging. The purpose of forging lubrication is to reduce friction between blank and die, and to decrease resistance of metal flow to die. The stress-strain curves at different temperatures are obtained by compressing tests. The friction factor between 1050 aluminum alloy and die material are determined at different temperatures by ring compression tests with graphite lubricants. The compressing and ring compressing tests are carried out by using the computerized screw universal testing machine. The finite element method is used to investigate the forming characters of the forging process. To verify the prediction of FEM simulation in the cylindrical heatsink forging process, the experimental parameters such as stress-strain curves and fiction factor, are as the input data during analysis. Maximum forging load and effective stress distribution are determined of the heatsink forging, using the finite element analysis. Finally, the cylindrical heatsink parts are formed by the forging machine under the conditions using finite element analysis.

Analytical Correction

A weak-rigid monolithic component is subjected to significant distortion after the removal of material. This condition is principally due to flexibility of the part and the release of initial residual stresses resulting from fabrication. This article reports a systematic study on the measurement of initial residual stresses and the distortion of a windshield frame part induced by material removal from the forged blanks of aluminum alloy 7085-T7452. A layer-removal method was employed to measure the stress profiles of the blank. The stresses after analytical correction were found to be closer to actual condition. The effect of material removal on distortion from stressed blank was investigated using the finite element analysis software ANSYS. The simulated results indicate that after the proportion of removed material exceeds 60%, part distortion becomes stable. The comparisons of the simulation with experimental data suggest sufficient agreement with conclusion that the use of finite element analysis proves to be an attractive and reliable method for predicting stress-induced distortion.

In the clinical field, articular cartilage has an important role in performance of most joints in the human body. In the present study, articular cartilage was excised from the knee joint of a bovine and tested in a tensile testing machine. The data obtained from the test was used to calculate the material properties of the cartilage. The material properites obtained from the experimental work were validated against the published experimental results in the literature. As the values from the experiment were in satisfactory agreement with the published data, it was concluded that the test protocol used in the experiment provides reliable data. Next, the material properties were implemented in finite element model of C3-C4 of cervical spine to examine if the finite element analysis can provide an accurate prediction of the behavior of the cervical spine. The stress and displacement results of the finite element analysis were consistent with the reported data in the literature. The location and the amount of the maximum stresses were examined and compared with the failure point of the materials.

Predictive power and final shape are very important in the forging process. This study used a finite element method to analyze the forging force, final shape and stress distribution of the cellphone shell forging at different temperatures. To predict the results of FEM simulation accurately, the stress flow and friction factor play an important role. The AL-6061 stress-strain curve at different temperatures was obtained from the compression test of the universal material testing machine. The friction factor between Al-6061 alloy and die is determined by ring compression test.The stress-strain curve and friction factor are applied to the finite element analysis of cellphone forging. Finite element analysis is used to determine the maximum forging load, effective stress distribution and shape of cellphone shell forging. Then the cellphone shell is forged with the parameters of finite element analysis results. Finally, the forging force and product shape are compared between the experimental data and the simulation results. The dimension of the cellphone shell agree with the initial design and the forming force does not exceed the maximum allowable forging load of the machine.
