Titanium alloys have been extensively explored and fabricated for application in several engineering fields. Its superior mechanical properties, Ti-10Mo-xCu alloy has potential applications in hip implants. Determining mechanical qualities via experimental methods takes a long time, especially when carried out in compression and tensile testing. Therefore, material design modeling using an MD simulation method approach is used to evaluate the mechanical properties of the compression and tensile tests of the Ti-10Mo-xCu alloy. In this research, material design through computer modeling is carried out at 300 K in the x <100> direction of the Ti-10Mo alloy with the addition of Cu composition at 3, 6, and 9 wt.% to evaluate the properties of the alloy. The simulation results of the Cu addition produces maximum stresses of 603, 160, and 236 Mpa, respectively. The experimental method in the compression test shows a decrease in the maximum stress after adding Cu to the Ti-10Mo alloy. It has the same trend value as the compression test outcomes on the experiment and MD simulation method. The result of tensile strength for the Ti-10Mo-xCu alloy are 7056.8, 7238.2, and 7433.1 Mpa, respectively. MD simulation of the results of crack propagation in tensile strength is successfully performed based on the increase at high strain until plasticity occurs in the alloy.
