All the nonlinear structural element types except trusses support temperature-dependent material properties. If this type of material is selected, you will define all the isotropic or orthotropic material properties at multiple temperatures in a tabular format. 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 material properties will be linearly interpolated between temperature values. The temperature values must cover the range of temperatures that will be encountered in the model. You can also import the material properties from a csv file by pressing the Import button. The data in the csv file must be formatted into 13 columns. The properties should be in the same order as they appear in the table.
