Notes:
Biological soft tissues like muscles and cartilages are anisotropic, inhomogeneous, andnearly incompressible. The incompressible material behavior may lead to some difficulties innumerical simulation, such as volumetric locking and solution divergence. Mixed u-P formulationscan be used to overcome incompressible material problems. The hyperelastic materials can be usedto describe the biological skeletal muscle behavior. In this study, experiments are conducted toobtain the stress-strain behavior of a solid silicone rubber tube. It is used to emulate the skeletalmuscle tensile behavior. The stress-strain behavior of silicone is compared with that of muscles. Acommercial finite element analysis package ABAQUS is used to simulate the stress-strain behaviorof silicone rubber. Results show that mixed u-P formulations with hyperelastic material model canbe used to successfully simulate the muscle material behavior. Such an analysis can be used tosimulate and analyze other soft tissues that show similar behavior
