Numerical Analysis of Recycled AA6061 Reinforced Alumina Oxide Undergoing Finite Strain Deformation Uniaxial Tensile and Taylor Cylinder Impact Tests

Abstract

Recycling aluminum is a topic of high interest due to the global demand for aluminum-based products. This approach presents a great opportunity to address the environmental issues caused by the primary production of aluminum made from bauxite ore. In recent years, many researchers have explored the recycling of aluminum alloys, including reinforcement, to achieve better results and improve properties. However, there have been limited efforts to predict the deformation behaviour of such materials numerically. It is generally agreed that advancements in numerical analysis are important to accelerate progress and establish the application of newly developed materials. Therefore, this study aimed to numerically predict the deformation behaviour of recycled aluminum alloy AA6061 reinforced with Alumina Oxide, subjected to finite strain deformation of uniaxial tensile tests at different strain rates (6x10-1s-1 to 6x10-3s-1) and Taylor Cylinder Impact at different impact velocities (190ms-1 to 370ms-1) using the LS-DYNA simulation code. In this numerical analysis, a Simplified Johnson-Cook model is adopted and characterized. The simulation results, which were validated against published experimental data, showed good agreement, establishing appropriate numerical prediction capabilities for recycled aluminum alloys AA6061 reinforced with Alumina Oxide.
