SUMMARY
The discussion centers on analyzing the effects of pressure on automotive tires using ANSYS Workbench, specifically with the Mooney-Rivlin material model. Users encountered convergence issues when applying high internal pressures, initially set at 0.7 MPa, which were resolved by reducing the pressure to 0.06 psi. The conversation highlights the importance of using a non-linear solver, increasing substeps, and accurately modeling the tire's composite structure for successful simulations. Participants also discussed the necessity of applying realistic boundary conditions and load steps to achieve convergence in the analysis.
