10.6. Compute Feature Boundary Strength Metrics

Group (Subgroup)

Statistics (Crystallographic)

Description

THIS FILTER ONLY WORKS ON Cubic m-3m LAUE CLASSES

This Filter calculates the same metrics as in the Find Neighbor Slip Transmission Metrics Filter. However, this Filter stores the values in the Face Attribute Matrix of a Triangle Geometry. The algorithm the Filter uses is as follows:

1. Find the two Features that are separated by a Face in the Triangle Geometry

2. Get the average orientation of both of the Features

3. Calculate the transmission metrics from both directions (i.e. Feature 1 to Feature 2 and Feature 2 to Feature 1)

4. Store the metrics in the Face map

5. Repeat for all Faces

Note: Each metric is calculated twice for the two different directions slip could approach the boundary. The values are stored on each Face in the Face map in a way that notes the direction (i.e., when Feature 1 has neighbor Feature 2 and when Feature 2 has neighbor Feature 1) because the direction across the boundary between the Features affects the value of the metric.

Luster-Morris Parameter (M’ Values)

The values are calculated as presented in [1].

Fracture Initiation Parameter (fip)

Three (3) fip values are computed as outputs to this filter. These are best explained in [2], see page 021012-4
