Chapter 18: Viscoelastic Analysis of an All-Ceramic Fixed Partial Denture (FPD)

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.

You can also perform this example analysis entirely in the Ansys Mechanical Application. For more information, see Viscoelastic Analysis of an All-Ceramic Fixed Partial Denture (FPD) in the Mechanical Technology Showcase: Example Problems.
