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) using the Ansys Mechanical application. To see this example solved using Ansys Mechanical APDL see Viscoelastic Analysis of an All-Ceramic Fixed Partial Denture (FPD) in the Technology Showcase: Example Problems. 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.
