“…Researchers have investigated the effects of various compaction methods, including pressure, temperature, and binder materials, on the properties of compacted swarf, such as their density and strength. [ 7–10 ] Ab Kadir et al [ 11 ] verified that the ratio of swarf in the powder significantly impacts the hardness and compressive strength of Al6061 samples. Figure a–c displays scanning electron microscopic images of compacted Al6061 samples with varying ratios of swarf in the powder.…”

Metal swarf has the advantage of being eco‐friendly due to their ability to be recycled and reused, in addition to being lightweight, energy‐absorbing, and cost‐effective. For practical applications in various industrial fields, effective and accurate modeling for each case should be developed in consideration of its physical properties. This study investigates the mechanical behavior of aluminum chip compaction employing a new computational simulation approach based on a pressure‐dependent porous continuum model. Two material parameters of densification rate (n) and ratio of shear modulus (m) were proposed and adjusted for different swarf. The numerical results show good agreement with the experimentally obtained axial stress – relative density relation of three various samples, demonstrating a close relationship between the parameters n and the chip geometry. This study can be applied for further investigation and analysis utilizing metal swarf of different geometries in various industrial applications.This article is protected by copyright.

Recycled aluminum will be a significant material choice for automobile body stamping because of its recyclability and low cost. In this paper, the cupping tests and tribological tests were used to study the evolution of defects in forming process and its influence on the properties of recycled aluminum alloy, Failure mechanisms of recycled aluminum alloy were analyzed, as well as the interaction between different lubricant additives and defects under oil lubricating conditions. According to the results, the defects of the recycled aluminum alloy, especially the impurity phase particles, can have negative effects on the properties of the sheets. The impurity phase particles are brittle and are prone to fracture, resulting in stress concentration. In addition, the binding with the matrix is weak, which destroys the continuity and leads to surface strain in the process of material flow, thus adversely affecting the quality of the cup. By physical adhesion and filling of the depressions, MoS2 solid lubrication additive improves forming and friction performance of the cup. The present study indicates how defects affect the cupping properties of recycled aluminum alloys, and it provides a theoretical basis for the improvement of the stamping lubrication process of recycled aluminum alloys.

“…The response can be anisotropic as a result these factors [18], [19]. Numerous efforts can be seen consider the influence of anisotropic characteristic, which has also attracted attention the user of metal structures including functionally graded natural fiber/epoxy (FGNF/epoxy) [19], [20], [43]. The response is complex since different behaviour is observable in different orientation, compared to isotropic material that has no preferred orientation [40], [41].…”

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.
