New materials can be created with scripting in Workbench. The data can be hard coded or imported.
The import would need to be parse the data into the correct parameters/properties, but there is no shortage of examples how to import csv data in python.
Here I just show how to go from the parameters to a WB material.
And to enhance this example, simply use the journaling/recording function in Ansys Workbench to figure out the requirements for more complicated material models, here a simple isotropic material is generated, Flubber.
The example assumes you have an analysis system already in WB and it has a Engineering Data container.
material_data = ['flubber', 22,1,0.3] # import data from csv
# parse into individual properties
mat_name = material_data[0]
Tref = material_data[1]
Emod = material_data[2]
Prxy = material_data[3]
system = GetSystem(Name="SYS")
engineeringData = system.GetContainer(ComponentName="Engineering Data")
newmat = engineeringData.CreateMaterial(Name= mat_name )
matlProp = newmat.CreateProperty(Name="Elasticity", Behavior="Isotropic", Qualifiers={"Definition": "","Behavior":"Isotropic"})
matlProp.SetData(SheetName="Elasticity", SheetQualifiers={"Definition": "", "Behavior": "Isotropic", "Derive from": "Young's Modulus and Poisson's Ratio"},Index=-1,Variables=["Temperature"],Values=[[str(Tref)+ "[C]"]])
matlProp.SetData(SheetName="Elasticity",SheetQualifiers={"Definition": "", "Behavior": "Isotropic", "Derive from": "Young's Modulus and Poisson's Ratio"},Variables=["Young's Modulus"],Values=[[str(Emod) + "[MPa]"]])
matlProp.SetData(SheetName="Elasticity",SheetQualifiers={"Definition": "", "Behavior": "Isotropic", "Derive from": "Young's Modulus and Poisson's Ratio"},Variables=["Poisson's Ratio"],Values=[[str(Prxy)]])
