Sas-Boca et al. [1] presented FEM simulation on wire drawing process and realized the half approach angle has a high influence on drawing force.
El-Domiaty et al. [7] studied the thermal aspects of the wire-drawing process, and the results can be used for process parameter selection with the aim of minimizing temperature rise.
Kleinermann et al. [8] used FEM simulation to solve inverse problems such as parameters identification, initial geometry, and tool shape design.
Beland et al. [10] performed an optimization study on cold drawing process of 6063 aluminum tubes for minimizing the axial stress in the drawn tube as well as the drawing steps.

Mg solute atoms are the major factor causing this effect in Al-Mg alloys.
It can be concluded that the Al-Mg-0.42wt%Cu alloy possesses the highest strength.
The addition of Cu does not affect the n̄ values, as the n̄ value of Al-Mg-0.42wt%Cu alloy is comparable with that of Al-Mg-0wt%Cu alloy, only 1.1% lower.
El-Sebaie and Mellor[26] reported some calculation results based on the assumption of instability under the plane strain condition at the bottom of the cup wall.

Apart from Penzien modal, El Naggar and Novak modal [2], Nogami modal [3], Boulanger modal [4] are also the typical preventatives of lumped parameter method.
In the paper, three seismic waves as El-Centro Wave, Nanjing Wave and Hyuga NADA-OKI Wave were chosen, and applied to the structure along the bridge, the waveform graphs and response spectra were shown in Fig.5, Fig.6, Fig.7, and Fig.8.
Under the excitation of Hyuga NADA-OKI Wave, the average moment increase 47.0% and 46.6% than El-Centro Wave and Nanjing Wave respectively.

The breakthrough curves generated were fitted with Adams-Bohart, Thomas, Yoon-Nelson, and Yan et al. models.
It can be seen from the plots that indeed the Yan et al. model fits well with the experimental data.
Calculated Yan et al. model parameters for each column runs.
