Assessing multiple approaches and various hyperelastic models for biomechanical properties of animal skin / Nor Fazli Adull Manan

The importance of understanding skin behaviour, either in biological domain or engineering field has led to many researches. Researches about the anisotropic and viscoelastic behaviour were carried out on human, animal or synthetic skin. The simple structure can look from outside, but complex anatomy when study in details under the skin layer. The complicated behaviour of skin such as highly non-linear, viscoelastic, inhomogeneous and anisotropic clearly shows the complexity behaviour of skin, especially when measuring and quantifying its bio-mechanical properties. Therefore, this research aims to quantify the Bio-Mechanical properties of animal’s skin via multiple approaches and adapting various hyperelastic constitutive models. Systematic methodology employed in this research starts with the experimental approach (in-vitro mechanical testing) followed by the analytical approach (theoretical derivation) then numerical approach (computational parameter quantification) and finally Finite Element simulation (skin model simulation)…
