“…The mechanical characteristics of the composites are evaluated using a universal mechanical testing apparatus (Shimadzu AG-X plus machine). Five samples of the silicone material Ecoflex 00-30 in dog-bone shape and five samples containing 70 wt % magnetic particles with a gauge length of 33 mm in compliance with ASTM D412 are investigated [59]. The test is carried out to compare the stresses under magnetic and non-magnetic conditions.…”

“…Meanwhile, allografts can be described as tissue of the same living organism that is human transplanted to another human and can be divided into three types in which epithelial or epidermal, dermal and composite. The different from two skin substitutes compared to autografts is it uses the same tissue from the living organism in which human to heal the wound [13,14,15]. The importance of design and fabrication skin substitute lead to studying the mechanical behaviour by Nadiah et.…”

“…The importance of design and fabrication skin substitute lead to studying the mechanical behaviour by Nadiah et. al [14] to investigate specific standard of measuring the properties of synthetic skin. The silicone rubber was used in determining two physical testing standards in which are ASTM D2209 and ASTM D412 [testing standard] involving uniaxial tensile testing and MATLAB programme to measure the material constant.…”

“…Hence, the investigation using hyperelastic material model will be useful in determining the mechanical behaviour of skin which are originally developed for rubber materials such as Neo-Hookean, Mooney-Rivlin and Ogden models; are commonly adapted for soft tissues [18,19,20,21,22,23,25]. A parametric study has been constructed in determining the mechanical behaviour of material using Neo-Hookean's strain energy function [14]. In that study, the contributions of material constant C 1 were evaluated by varying its using Neo-Hookean constitutive equation.…”

Skin performs multiple important functions for our body and that might be the main reason for it complex structure and unique mechanical behaviour. There have been a lot of studies about skin mechanical behaviour but skin deformation behaviour and its dynamic stress under low impact loading is still not well understood. This paper aims to review past research related to skin investigation, which ultimately leads to proposing a research framework in determining the dynamic stress of skin and synthetic skin under low impact loading. In the first stage, the literatures related to skin substitutes and skin hyperelastic properties were reviewed, summarise d and reported. The past research related to numerical analysis using hyperelastic constitutive models such as Neo-Hookean, Mooney-Rivlin and Ogden model to quantify skin mechanical behaviour were discussed. Next, the literatures related to determining dynamic stress as well as the specimen specification were reviewed and reported. Finally, based on these reviews, a research framework to determine the dyn amic stress of skin and synthetic skin under low impact loading is proposed. The information provided in this paper could contribute significant fundamental knowledge about skin behaviour and the preparation to perform experiments in understanding the dynamic stress of skin under low impact loading.

The utilisation of bamboo has the potential of improving the properties of silicone. However, a thorough investigation has yet to be reported on the mechanical properties of bamboo silicone biocomposite. This study was carried out with the aim to quantify the tensile properties and assess the tensile behaviour of bamboo silicone biocomposite using Yeoh hyperelastic constitutive function. The specimens were prepared from the mix of bamboo particulate and pure silicone at various fibre composition ratio (0wt%, 1wt%, 3wt% and 5wt%) cured overnight at room temperature. A uniaxial tensile test was carried out by adopting the ASTM D412 testing standard. The Coefficient of Variation, CV, and the Coefficient of Determination, r 2 , were determined to assess the reliability of the experimental data and fitting model. The results of the determined Yeoh material constants for 5wt% specimen is found to be C 1 = 12.0603×10 -3 MPa, C 2 = 8.7353×10 -5 MPa and C 3 = -11.6165×10 -8 MPa, compared to pure silicone (0wt%) C 1 = 5.6087×10 -3 MPa, C 2 = 8.6639×10 -5 MPa and C 3 = -7.6510×10 -8 MPa. The results indicate that the bamboo fibre improves the stiffness of the silicone rubber by 115 percent. A low variance was exhibited by the experimental data with a CV value of less than 8 percent. The Yeoh Model demonstrated an excellent prediction of the elastic behaviour of bamboo silicone biocomposite with a fitting accuracy of more than 99.93 percent.
