Multibody dynamics analysis (MDA) models how muscle forces affect skeletal structures. This study used MDA to show varying muscle representations significantly alter stress fields in macaque skulls during biting.

Area of Science:

  • Biomechanics
  • Computational modeling
  • Craniofacial research

Background:

  • Finite element analysis (FEA) is common for evaluating stress and strain in anatomical structures.
  • Confidence in FEA results depends on realistic applied loading conditions.
  • Multibody dynamics analysis (MDA) offers a novel approach to model complex loading scenarios.

Purpose of the Study:

  • To investigate the influence of different muscle representations on stress fields in a macaque skull model.
  • To assess the impact of varying muscle fiber modeling (single, multiple, wrapped) on mechanical loading.
  • To validate the application of MDA in biomechanical analyses of craniofacial structures.

Main Methods:

  • Developed a three-dimensional computer model of a macaque skull (Macaca fascicularis).

  • Applied multibody dynamics analysis (MDA) to simulate varying muscle forces and predict joint/bite forces.
  • Investigated different muscle fiber representations: single, multiple, and wrapped fibers.
  • Assessed the impact of these muscle representations on stress fields using finite element analysis (FEA).

    • Main Results:

    • MDA models demonstrated that muscle forces and internal group forces vary significantly with jaw gape.
    • The anterior strands of the superficial masseter were found to experience greater loading than posterior strands.
    • Modeling temporalis muscle wrapping altered muscle force direction and induced compressive forces on cranial bones during biting.

    Conclusions:

    • Multibody dynamics analysis (MDA) provides a robust method for applying realistic muscle forces in biomechanical studies.
    • Different muscle fiber representations significantly influence predicted stress and strain fields in craniofacial skeletons.
    • MDA enhances the physiological relevance of engineering techniques like FEA for understanding skeletal loading.
