To establish the "Link" between the crack and the water pressure:
Pressure Distribution: The Crack Link interpolates the water pressure across the finite element mesh on the crack surface. This allows for non-linear pressure distributions, which are critical for deep-seated cracks that intersect varying phreatic levels.
In Slide3, a Crack is defined as a planar surface or a polygonal volume that bisects the mesh. Unlike a simple material boundary, a Crack introduces a discontinuity in the displacement field. The software treats the interface as a potential failure plane where slip can occur independently of the surrounding rock mass.
“Crack links transform a scattered fracture cloud into a deterministic failure pathway – Rocscience lets you generate, detect, and analyse them in minutes.”
