The experimental data-table option (TB,EXPE) allows you to input experimental data. The data is used with other material models.
Initiate the experimental data table, then specify the appropriate
experimental data type (TBOPT), as follows:
| UNIAXIAL - Uniaxial experimental data |
| BIAXIAL - Equibiaxial experimental data |
| SHEAR - Pure shear experimental data, also known as planar tension |
| VOLUMETRIC - Volumetric experimental data |
| SSHEAR - Simple shear experimental data |
| UNITENSION - Uniaxial tension experimental data |
| UNICOMPRESSION - Uniaxial compression experimental data |
| GMODULUS - Shear modulus experimental data |
| KMODULUS - Bulk modulus experimental data |
| EMODULUS - Tensile modulus experimental data |
| NUXY - Poisson's ratio experimental data |
Enter the data (TBPT) for each data point. Each data point entered consists of the independent variable followed by one or more dependent variables. The specific definition of the input points depends on the requirements of the material model associated with the experimental data.
You can also define experimental data as a function of field variables. Field-dependent data are entered by preceding a set of experimental data (TBFIELD) to define the value of the field.
