Drop Impact Resistance for TZM, Al7075, and AZ31 Alloys

Project Overview

This project addressed the critical need for advanced materials in aerospace components requiring high impact resistance. An analysis was conducted to evaluate the performance of Titanium-Zirconium-Molybdenum (TZM), Aluminum 7075, and Magnesium AZ31 alloys. The simulation modeled a 1 kg cylindrical mass dropping from 1.5 meters onto 5mm thick target plates of each material, analyzing total deformation, equivalent plastic strain, Von Mises stress, and internal energy absorption. TZM consistently outperformed both Aluminum 7075 and Magnesium AZ31, demonstrating approximately two times lower deformation, plastic strain, and absorbed internal energy. This superior stiffness and durability position TZM as an ideal candidate for critical aircraft components exposed to mechanical impact, such as structural panels, battery shielding, or high-speed drone skins, enhancing safety and longevity in emerging aerospace platforms.
