ModeMixity

Source: models/solid_mechanics/traction_separation_law/ModeMixity.py

Mode-mixity ratio \(\beta = \delta_s / \delta_n^+\) in the opening branch; \(\beta = 0\) in compression. Uses a safe-divisor where-and-detach pattern so the masked-off compression branch does not trip on a division by zero.
