Hyperelastic constitutive analysis of silicone sheet as skin substitute / Siti Noor Azizzati Mohd Noor

Silicone Rubber is a potential skin substitute material, whereby its mechanical behaviour is also difficult to characterize. This study pioneers in its attempt to investigate the mechanical properties of Silicone Rubber materials via the integration of experimental, numerical and analytical approach...
