Recycling aluminium is a topic of high interest for numerous researchers to cope with the high demand for usage of its primary sources, and to overcome the environmental issues at the same time. Yet, the deformation behaviour is lacking in the literature and thedevelopment of an appropriate numerical analysis of such recycled material is also missing without this information. It is very important to understand the behaviour of the recycled aluminium alloy under various deformation condition before any application is applied. The numerical analysis data is also important for the ease of future application simulation work. Thus, the aim of the present study is to characterize the deformation behaviour of the recycled aluminium alloy under different tensile loading condition and to model a numerical analysis for the prediction of the deformation behaviour of recycled AA6061. The deformation behaviour of the recycled AA6061 was tested over two different loading speed (1.5 mm/min and 15 mm/min) and different elevated temperature (100°C –300°C). The recycled AA6061 exhibits strain-rate dependence behaviour with mild-ductile-elastoplastic behaviour within the considered loading condition. The degradation of tensile properties is quite significant, which is due to crystallinity. Based on the experimental findings, the material model MAT_098 of Simplified Johnson-Cook model, was adopted and the input parameters were characterized. The simulation results were validated against the experimental data. A good agreement between the experimental and numerical results are obtained. The outcome of numerical analysis is important to prove a strength model is still relevant to predict the deformation behaviour of such recycle material. Further, it showed that further manufacturing advancement is required on the experimental part since an anisotropic parameterare still unavailable, yet vital for consideration.
