MODELING AND SIMULATION OF SKELETAL MUSCLE BASED ON COMBINED EXPONENTIAL AND POLYNOMIAL MODEL

Abstract

With the aim to build an accurate skeletal muscle simulation model, the biomechanical modeling and solution method of skeletal muscle were developed. First, the Mooney–Rivlin model, polynomial model, exponential model, logarithmic model, combined exponential and polynomial model were compared. The biomechanical model of skeletal muscle was built by combining the exponential and polynomial models. Second, the geometric non-linearity problem and material non-linearity problem of the biomechanical model were solved by using the finite element method. The program for this solution was implemented using Visual Studio 2012. Finally, the simulation results were compared to the experimental results. The maximum error between the simulation curve and the experiment stress–strain curve was 0.00149[Formula: see text]MPa. Finite element simulation for the lateral femoral muscle was conducted using the program developed in this study.
