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 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.
