Statistics Filters (Crystallographic)
This filter calculates the Schmid Factor of each Field given its average orientation and a user defined loading axis. The Schmid Factor is the combination of the component of the axial force F that lies parallel to the slip direction and the component that lies perpendicular to the slip plane. The equation for the Schmid Factor is given as:
Schmid Factor = (cos φ cos λ) The angle φ is the angle between the tensile axis and the slip plane normal, and λ is the angle between the tensile axis and the slip direction in the slip plane.
The filter determines the Schmid Factor for each Field by using the above equation for all possible slip systems (given the Field's crystal structure). The largest Schmid Factor from all of the slip systems is stored for the Field.

Type | Default Name | Description | Comment | Filters Known to Create Data |
---|---|---|---|---|
Field | FieldPhases | Phase Id (int) specifying the phase of the Field | Find Field Phases (Generic), Read Field Info File (IO), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding) | |
Ensemble | CrystalStructures | Enumeration (int) specifying the crystal structure of each Ensemble/phase (Hexagonal=0, Cubic=1, Orthorhombic=2) | Values should be present from experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute. | Read H5Ebsd File (IO), Read Ensemble Info File (IO), Initialize Synthetic Volume (SyntheticBuilding) |
Field | AvgQuats | Five (5) values (floats) defining the average orientation of the Field in quaternion representation | Filter will calculate average quaternions for Fields if not already calculated. | Find Field Average Orientations (Statistics) |
Type | Default Name | Description | Comment |
---|---|---|---|
Field | Poles | Three (3) values (ints) giving the crystallographic pole that points along the user defined loading direction. | |
Field | Schmids | Value of the Schmid Factor (float) for the most favorably oriented slip system (ie the one with the highest Schmid Factor). | Only the Schmid Factor was used in determining which slip system's Schmid Factor to report. The critical resolved shear stress for the different slip systems is not considered. |
Field | SlipSystems | Enumeration (int) of the slip system that has the highest Schmid Factor | Numbers correspond to specific slip systems for the different crystal structures as follows: |
