Estimation of Viscous Properties of Skin and Subcutaneous Tissues via Uniaxial Stress Relaxation Tests
چکیده
INTRODUCTION Using traditional experimental methodologies [1,2,3], the skin has to be separated from the subcutaneous tissues in order to determine the tissues’ viscoelastic properties. Thus, the complex collagen fiber network in soft tissue could be damaged when the skin is separated from the subcutaneous tissue. Therefore, the viscoelastic properties of the skin and subcutaneous tissues measured using isolated samples may be different from those in physiological conditions. The purpose of the present study is to estimate the viscous behaviors of the skin and the subcutaneous tissues using composite tissue specimens.
