Viscoelastic Analysis of an All-Ceramic Fixed Partial Denture

This example problem demonstrates the fictive-temperature material model using the Tool-Narayanaswamy (TN) shift function to examine residual stresses in an all-ceramic fixed partial denture (FPD). A coupled-field solution process, including transient thermal and nonlinear structural analyses, is used in the problem simulation.

The following capabilities are highlighted:

  • Using the fictive temperature model for viscoelastic material.
  • Running a transient thermal analysis to determine the temperature profile at various time steps.
  • Applying thermal analysis results as temperature loads for structural analysis.
  • Running a nonlinear structural analysis to determine residual stresses due to thermal loading.
