A comparative study of all three methods shows the effectiveness of the beam-to-beam simulation (Case 3).

Displacement

The total deformation plots are shown for the three models. The values are similar for all three.

von Mises Stress

Von Mises stress (SEQV) is plotted for the three models. The plots show that maximum stress occurs at a similar location in all three models, and the overall stress pattern is similar.

Computational Time

The following table compares simulation time and cumulative iterations for the three cases.

The above data shows that the beam-to-beam simulation (Case 3) is less computationally expensive than the solid model.

Conclusion

The comparison of von Mises stress and computation time for these models illustrates that similar results and reduced computation time can be achieved by using a simplified beam model and beam-to-beam contact.
