Abstract and keywords

A better characterisation of skeletal muscle is required to improve the accuracy of human body models used for virtual modelling. In this study, the quasi-static and dynamic properties of porcine muscle tissue have been investigated using uniaxial unconfined compression tests performed on samples oriented at various angles from the muscle fibre direction. Quasi-static tests show that the weakest direction is at 45° from the fibre direction. A model based on linear elasticity for transversely isotropic bodies extended with strain dependent Young's moduli fits the quasi-static data very well. Results from the dynamic tests show that muscle tissue presents anisotropic viscoelastic behaviour.
