Skeletal Muscles Modeling for Isogeometric Analysis

Abstract

This research uses only surface control points to parameterize the 3D geometry of a muscle body. Extension from surface to interior is achieved using a harmonic interpolation in cross section and in the lateral direction using NURBS. This representation preserves geometric smoothness, and allow muscle fiber distributions to be easily parameterized. Utilizing this geometric method also provides the framework for implementing material properties using an interpolative-style scheme. Upon supplying constitutive models these models can be directly used in analysis.
