This page is applicable to the following temperature-dependent material models:
- Elastic
Thermoelastic - Elastic Temperature Dependent Orthotropic
- Viscoelastic Linear Thermal Viscoelastic Isotropic
- Viscoelastic Linear Thermal Viscoelastic Orthotropic
- Plastic Thermoplastic
- Viscoplastic Thermal Creep Viscoplastic
In addition, the Thermal Creep Viscoelastic material model is temperature-dependent and is discussed on a separate page.
All the nonlinear structural element types except trusses support temperature-dependent material properties. If one of this type of material models is selected, you will define all of the isotropic or orthotropic material properties at multiple temperatures in a tabular format. The properties that you must specify are the same as those applicable to non-temperature-dependent isotropic or orthotropic material models.
Each row in the table contains the properties associated with a single temperature:
- You can add a row to the bottom of the table by pressing the Add Row button.
- You can delete a row from the table by selecting the row and pressing the Delete Row button.
- The temperature values must be input in ascending order.
- The data can be sorted according to increasing temperatures by pressing the Sort button.
- The temperature values must cover the range of temperatures encountered in the model.
- The material properties will be linearly interpolated between temperature values.
You can also import the material properties from a CSV file (comma-separated values) by pressing the Import button.
