 This dataset contains several microstructure treatments:
-1. `variable_radius.zip` - Ten microstructures with defects of variable radii.
-2. `variable_number.zip` - Ten microstructures with different numbers of defects. 
+1. `variable_radius.zip` - Ten microstructures with defects of variable radii, from 0.01 mm to 0.5 mm.
+2. `variable_number.zip` - Ten microstructures with different numbers of defects, from 20 to 200. 
 3. `circular_defects.zip` - This data contains image data of 1000 samples of microstructures with 100 circular porosity defects having their radii uniformly distributed in the range 0.1 – 0.5 mm, and their corresponding strain fields.
