The Engineering Data enables you to define Isotropic and Orthotropic Elasticity as well as Stress and Strain limits as a function of up to nine user-defined scalar field variables. Engineering Data pre-defines Temperature, Degradation Factor and Shear Angle fields. If necessary, you can add a custom field variables. From within ACP, the custom field variables have to be defined as described by Field Definition Object Properties for Element- or Layer-wise definitions. From the Workbench-level, External Data components can be used to define custom field variables. Please note, however, that External Data components do not permit layer-wise field definitions.
