Table 3 Boundary conditions and static loadings for initial stress states.
From: Assessment of the finite element solutions for 3D spontaneous rupture using GeoFEM
Boundary surface | Loading/constraint direction | Type of boundary conditions | Quasi-static loading step for initial normal/shear stresses |
|---|---|---|---|
z = +20 km | −z | constant pressure |  |
z = −20 km | z | fixed displacement |  |
y = ±20 km | y | fixed displacement |  |
x = ±30 km, z > 0 | x | controlled displacement | u x 0 |
x = ±30 km, z > 0 | −x | controlled displacement | −u x 0 |
