Feasibility study of femur bone with continuum model

Area of Science:

• Biomechanics
• Computational Mechanics
• Orthopedic Engineering

Background:

• Bone geometry presents significant complexity, challenging traditional continuum modeling approaches.
• Current methods often rely on simulations or experimental tests, highlighting the need for simplified continuum models.
• Developing accurate continuum models for bone structures is a long-standing research goal.

Purpose of the Study:

• To investigate the suitability of a suggested beam model for simulating femur bone geometry.
• To assess the potential of this approximated beam model as a link to continuum theories for beams.
• To evaluate the feasibility of using this model for both static and dynamic analysis of femur bones.

Main Methods:

• A suggested beam model was applied to femur bone geometry.
• Static analysis was performed on the femur bone using the beam model.
• Dynamic analysis (vibration analysis) was conducted on the femur bone using the beam model.

Main Results:

• The suggested beam model yielded acceptable results for vibration analysis in most cases.
• Static analysis using the beam model showed a mean difference of approximately 16% compared to other methods.
• The study provides initial data on the model's performance in static and dynamic scenarios.

Conclusions:

• The investigated beam model shows promise for dynamic analysis of femur bones.
• Further refinement is needed for accurate static analysis of femur bones using this continuum approach.
• This research represents a foundational step towards developing continuum-based beam models for bone biomechanics.
