Abstract: Bio pad wound dressing is one of the current material in wound healing technology. This aim of this paper is to study the effects of dimethicone cross polymer on the biomaterial and to investigate the mechanical properties of the bio pad by the integration of experimental and numerical approach. In vitro uniaxial tensile test was performed to compute the stress-stretch response of the materials using ASTM D412 standard. The determination of material constants for the materials via numerical approach can be done by comparing with two hyper elastic constitutive models (Ogden and Neo-Hookean). The results show that Ogden’s exponent and coefficient for the subject estimated to be (μ = 0.434 MPa, α = 1.299) for Sample 1, (μ = 0.428 MPa, α = 1.424) for Sample 2, (μ = 0.463 MPa, α = 1.256) for Sample 3 and (μ = 0.633 MPa, α = 1.001) for Sample 4 respectively. Meanwhile, value of material constants for Neo-Hookeen were estimated to be (C1 = 0.00814 MPa), (C2 = 0.0121 MPa), (C3 = 0.00597 MPa) and (C4 = 0.00739 MPa) for Sample 1, Sample 2, Sample 3 and Sample 4 respectively. Therefore, this study could be useful in future studies in analysis of healing especially in dermatology area.
