Mechanical properties of sheep skin in compression Sakata, Kenji
Abstract
The mechanical properties of sheep skin in compression were investigated by two methods; a stress strain method and a cyclic stress fatigue method. It was shown that the skin behaves like a linear viscoelastic material for small loads, however, for large loads it behaves nonlinearly and the strain is essentially a logarithmic function of load. The effect on the skin of treatment with several solutions and enzymes were also investigated and characterized statistically. By the cyclic stress fatigue method the dependency of sheep skin on the previous history, which is axiomatic for biological materials, was investigated and it was shown that the fatigue behaviour of sheep skin is essentially a logarithmic function of time. Based on the experimental data, a mechanical model for sheep skin was proposed and the simulation of the model was carried out using an analog computer. By comparing the experimental data with the simulation results, the proposed model was shown to represent the experimental results satisfactorily.
