Pore orientation distribution under different deviatoric stresses for (a) W-L and (b) L-W paths. The rose diagrams illustrate the directional preference of pores. The radial distance from the center in each angular segment (10° intervals) represents the percentage of the total number of pores oriented within that directional range.
