“…Finite Element Analysis was conducted upon different geometric configurations (shown in Table 1), and the energy absorbed by each specimen when subject to a Charpy Impact test was noted. The reference specimen shows a value of 26.30 J, which is a 1.16% deviation from the experimental value [24], and is within acceptable error limits, thereby further validating the material model used.…”

Biological materials such as nacre, found in mollusk shells and Bouligand structures, found in the armor of many arthropods, exhibit values of toughness that are much higher than their constituent materials. This is achieved via specific arrangements and combinations of natural materials. In all biomimetic studies seen in literature so far, any one type of material alone is chosen for mimicry. The present work aims to create a set of biomimetic designs that incorporate macroscopic features of both nacre and Bouligand structures, so as to achieve toughness amplification in the given material. Finite element analysis (FEA) of relevant geometric designs are initially performed using ABAQUS software and experimental validation of the most promising model (which was found to show a 46.15% improvement over the reference model) is done. The testing method selected for both simulations as well as experiment is the Charpy impact test (ASTM E23).

“…Upon impact, the energy absorbed by the specimen was found to be 38 J. This is a 46.15% increase over the base value of bulk aluminum alloy, which is 26 J [24]. The energy absorbed by the FEA model was found to be 36.60 J.…”

“…The testing operation was conducted using Rockwell hardness machine. The results obtained from Rockwell hardness test method and three indentations are presented in Figure 4 [41]. The results of hardness of the aluminium alloy specimens that quench in water, shea nut oil and palm oil at a temperature of 530˚C were increased.…”

Weight reduction and material substitution were increasing trends in the automotive industry due to the growing demand for more fuel-efficient vehicles to reduce energy consumption nowadays. The characteristic properties of aluminium alloy which includes high strength stiffness to weight ratio, good corrosion resistance, and high recycling potential make it the ideal candidate to replace the other materials (Steel or copper) currently used in cars. The replacement to aluminium alloy parts is on par to the weight reduction demand within automotive industry. The focus on lightweight had also brought the attention on the high strength Aluminium alloy. Its high mechanical properties and excellent strength to weight ratio had made it suitable for car frame parts. In order to improve its mechanical properties, the heat treatment technique make it the suitable process to implement in aluminium alloy for produce the car body parts. The process of heat treatment was same as hot stamping technique which is this process was to improve its mechanical properties. Hence, in order to define and identified the heat treatment technique available, this paper had reviewed on the development of forming process and heat treatment condition applied toward aluminium alloy throughout the years.

“…This prevents solid-state diffusion and phase precipitation. Quenching results in saturated solution and allows for increased hardness and improved mechanical properties of the metal (Abubakre et al, 2009 (Charles, 1995). The corrosion current density (j corr ) and corrosion potential (E corr ) were calculated from the Tafel plots of potential versus log current.…”

The electrochemical corrosion behaviour of untreated, quenched and annealed cold rolled 1060 aluminium specimens was studied through weight loss measurement, potentiodynamic polarization technique and optical microscopy in 0.5, 1, 1.5 and 2M H 2 SO 4 and HCl solutions. Data obtained from the tests show that the quenched specimens had the highest corrosion resistance as a result of its hardened surface due to retained saturated solid solution. The untreated aluminium specimens exhibited a lower corrosion resistance than the quenched specimens though the corrosion rates from HCl solution are generally higher than values obtained from H 2 SO 4 . Annealed specimens had the highest corrosion rate as its passive protective film resulting from the rearrangement of its microstructural constituents could not sustain the aggressive attack of corrosive anions within the acid solution. Micrographs from optical microscopy showed a severely deteriorated annealed morphology resulting from depletion of the grain boundary. Corrosion pits were observed in the untreated specimens while the quenched specimens showed limited deterioration due to general corrosion.
