Simulation Results
- Displacement Contours:
- The T-Rex model exhibits significant displacements in the tail region, with values ranging from 2.92e-01 to 3.00e-01 meters.
- Smaller displacement ranges are observed in other parts of the body, particularly around the hips and legs.
- Stress Distributions:
- The stress distributions show high stresses (up to ~10 MPa) concentrated near the tail tip, indicating yielding or plastic deformation.
- Lower stress values (~1-2 MPa) are present throughout the rest of the model.
Conclusion
The LS-DYNA simulation "dinosolid/movie_047.mp4" models a T-Rex subject to displacement at its tail tip. The results show significant displacements and stresses in the tail region, indicating yielding or plastic deformation. The simulation provides valuable insights into the mechanical behavior of dinosaurs under various loading conditions. |
