Effect of Temperature and Tanning Agent on Mechanical Properties of Animal Skin

Abstract

Open exposure to the extraordinary amount of the heat under the sun can causes the damage to the skin and lead to diseases. The analysis of the mechanical properties on cow skin which investigated by analyzing the uniaxial tensile test in order to produce the outcome based on the situation stated. Besides that, cow skin was selected in order to compare with the previous study on sheep skin. The aim of the study is to investigate the effect of varies temperature on mechanical properties of the animal skin. Experimental and numerical is part of the integration process of the data. Uniaxial tensile test was performed to measure the basic mechanical parameter of stress-stretch by according to the ASTM D2209-00 testing standard. Other than that, the hyperelastic constitutive model Arruda & Boyce (A&B) equation is simplified via numerical approach for finding the material parameter. A graph of Stress-Stretch (σ-λ) plotted for curve fit with the experimental data to obtain the mechanical properties of parameter. Overall, the samples applied with lanolin coating is more elastic even though it dried at 40oC compared to the sample sets without lanolin coating. With having the specific mechanical data of the skin by computational program and analysis it become more reliable by showing the real skin behavior to the variable.
