“…It is common knowledge that a thinner plate requires less energy for failure compared to a thicker plate [39,40]. When the bullet comes into contact with the plate, the plate experiences fracture faster if it is thinner.…”

This study aims to establish the perforation behaviour of direct recycled AA6061 to help establish the properties of the current most optimized direct recycled AA6061 through the hot press forging technique. This was achieved by subjecting direct recycled AA6061 plates of varying thickness to high-velocity impacts using a single-stage gas gun setup. The impactor is a hemispherical steel projectile of 13mm in length and 8.5mm in diameter. Plates of 3,4,5 and 10mm thickness were tested at velocities ranging from 120 m/s to 402 m/s. The deformation profiles of the impacted plates were captured and analyzed to quantitatively establish the perforation behaviour of recycled AA6061 plates. The plates showed irregular and non-axis symmetric patterns of deformation hinting the material exhibits anisotropic properties. The changes in the deformation profile were investigated in relation to changes in impact velocities and plate thickness were made to understand how they impact the profile. The deformation area was observed to be decreasing when the bullet impact velocity was increased. Higher velocity impact events lead to more material ejection from the plate in the form of fragmentation. Additionally, the deformation zone was observed to be getting smaller with an increase in the thickness of the plate. Thicker plates were found to have more fragmentation compared to thinner plates. Ductile failure characteristics such as petal formation and plugging were observed along with brittle characteristics such as fragmentation and conal fractures. Lower-velocity impacts lead to more energy absorbed by the target plates. Thicker plates observed more of the bullet’s energy. Through experimentation, the deformation behaviour of the directly recycled AA6061 material was established. This data can be used as a base for further research into the material’s behaviour characterisation.

Compaction force generated by blasting load requires strong material such as steel to act as a plunger to spread the force evenly. The problem with this method is retaining the plunger's original dimension from intolerable deformation. This paper uses ABAQUS software to study the ability to predict the response of solid cylindrical aluminium bars (6061) subjected to different close-in blast loads. The solid cylindrical aluminium bars treated as a plunger were evaluated numerically using a combination of the finite element method (FEM) and smoothed particle hydrodynamic (SPH) methods. The plunger was simulated using the Johnson-Cook (J.C.) model, and Jones-Wilkins-Lee (JWL) equation parameters modelled the explosive. Field tests were conducted by detonating explosives of two different weights, which are 100g and 250g, in the designated blast area. Both data and observation were compared and analysed regarding deformation behaviour in term of dimension difference and fracture. Based on the graph of the deformation dimension versus the plunger length, the deformation trend shows a very close relation between numerical and experimental data with a percentage error of less than 4%. The fracture mode generated using FEM is comparable to the actual specimen. This fracture mode can be described as similar to the behaviour of the specimen obtained using the Taylor impact test. Thus, it can be concluded that the numerical analysis performed for this study is consistent with the actual results.

Crash-dynamics research has always concentrated significantly in the safety, survivability of passengers in a car crash. To identify the capability of energy absorption of a crash box, a thin-walled structure will be modeled and simulated by ABAQUS software. Investigate the influence of material, cross-sectional, thickness factors on the energy absorption capacity of the tube, using MCDM – Multi-Criteria Decision-Making to get the best option and testing the improvement while filling the tube with Foam material. In this study, beside the cross-sectional, aluminum alloys and steel materials and thickness are factors that influence the energy absorption evaluation criteria, the foam material with difference density are surveyed to compare effectiveness between the foam-filled and hollow crashboxes. The results show that the folds of the foam-filled tube after deformation along the compressive direction will be more continuous and stable. More, the higher foam density, the greater the energy absorption. This prevents the crashbox from deviating from the direction of the force, help directing the collapse of the tube, thereby improving energy absorption without significantly increasing the weight of the structure.
