Abstract

Understanding the origins of the multiaxial material properties of soft tissues is crucial for quantifying the tissue material properties that govern the material behavior for acurate predictive modeling of the biological systems. Unlike many engineering structural materials, biological materials exhibit complex material behavior due to structural anisotropy and various interactions between each of the microstructrual units of the tissue. Therefore, this study aims to quantify the shear material behavior of rabbit patellar tendon under simple shear loading along the fiber direction and perpendicular to the fiber direction and to understand the role of tissue shearing and its contribution to the overall mechanical behavior of the tendon. It was hypothesized that tendon demonstrates anisotropic material response under simple shear. Results suggests that tendon exhibits direction-dependent viscoelastic shear properties, reflecting structural anisotropy. The data obtained from our present study could be used for development of constituent models using internal state variable theory.
