Fiber-Based Modeling of Muscles in the Musculoskeletal System
The aim of this contribution is to present a fiber-based modeling approach for the dynamic behavior of muscles within the musculoskeletal system. We represent the skeletal system as a rigid multi-body system which is actuated by muscles. We model each muscle as an one-dimensional cable with variable cross section undergoing large deformation and strains. In order to avoid penetration of the muscles and the skeleton, contact is considered. We use our framework to conduct a dynamic forward simulation of a simple upper limb model.
