Material

Material is the basic entity affecting the behaviour of the structure. It is subsequently applied to a chosen profile (StructuralCrossSection). The user can use a pre-defined material or change the properties to get a custom one. The predefined materials correspond to materials defined in particular technical codes.The specification in excel:
