Area of Science:

• Biomechanics
• Computational Modeling
• Muscle Physiology

Background:

• Skeletal muscle mechanical properties are crucial for understanding movement and injury.
• Existing models often lack the fidelity to capture complex muscle deformations accurately.

Purpose of the Study:

• To develop and validate a novel computational model for skeletal muscle mechanics.
• To enhance the accuracy of simulating muscle deformation and behavior.

Main Methods:

• Proposed the HVisc-MSM (Hexagonal Viscoelastic Muscle Simulation Model).
• Utilized regular hexagonal topological patches and spring modules with recovery capabilities.
• Validated through soft-body model simulations, longitudinal stretching, and in-plane shearing.

Main Results:

• The HVisc-MSM demonstrated effective simulation of muscle mechanical behaviors.
• The model showed higher fidelity in representing real mechanical deformation compared to existing models.
• Effectiveness verified through diverse simulation scenarios.

Conclusions:

• The HVisc-MSM provides a more accurate and high-fidelity representation of skeletal muscle mechanical behavior.
• This advanced modeling approach has significant implications for biomechanical research and applications.
• The study successfully bridged experimental, modeling, and simulation perspectives for muscle mechanics.
