The objective of this project was to analyze the mechanical behavior of a snap-fit bag buckle under applied loads using SOLIDWORKS Simulation.
To reduce computational time while maintaining result accuracy, the study was performed in 2D using a Nonlinear Dynamic analysis.
This approach allowed a realistic evaluation of stress distribution, deformation, and contact behavior between the buckle components during snap engagement.
Project Workflow:
- The buckle was modeled in SOLIDWORKS using a standard snap-fit design.
- The model was converted to 2D to reduce simulation time while keeping the results accurate.
- A Nonlinear Dynamic study was used to study large deformations and contact between parts.
- Material properties and loads were applied to replicate real working conditions.

Simulation Output:
Observations:
- The analysis highlighted stress concentration regions around the locking arms of the buckle.
- The deflection pattern showed smooth engagement with minor elastic deformation.
- The contact pressure distribution indicated areas that may require geometric refinement.
- These results help in optimizing the buckle shape and material selection for improved performance and durability.
Key Takeaway:
Performing nonlinear simulations in SOLIDWORKS Simulation enables engineers and learners to understand how snap-fit mechanisms behave under real-world conditions.
Such analyses provide valuable insights that support better design validation, optimization, and product reliability even before prototyping.
