  1. Tennis Racquet Finite Element Analysis Samuel R. Wilton

  2. Tennis Physics - Impact Force Newton’s Second Law Impulse-Momentum Simplified Impulse Force

  3. Material Properties Complex Composite Material System Carbon Fiber Reinforced Plastic (CFRP) Silicon Dioxide Nanoparticles Titanium Aluminum Kevlar

  4. String Tension

  5. Modeling Geometrically accurate 3D solid model created with Solidworks

  6. Finite Element Analysis Impact Force Modeled as Point Forces 500N String Tension Modeled as Pressure Distribution -1.00 MPa

  7. Part 1 - String Tension FEA

  8. String Tension Loading - FEA Deformed Shape

  9. String Tension Loading - FEA First-Principle Stress

  10. Part 2 – Ball Impact FEA

  11. Impact Force - FEA Vector Sum Displacement

  12. Impact Force - FEA Von-Mises Stress

  13. Non-FE Verification Intermediately Loaded Cantilever Beam

  14. Limitations • No 3D model for strings • No transient analysis • Rigid boundary conditions • Approximated

  15. Conclusions • Tremendously interesting results • Stress concentration correlates to design • Uncanny accuracy of beam approximation • Less than 7% error between beam and FE model • Transient Analysis would substantially benefit the finite element model. • More realistic modeling of strings and applied loads would improve model accuracy and enrich results.

  16. Ultra Slow-Motion
