concreteproperties.utils.split_geom_at_strains_ultimate(geom: CPGeom | CPGeomConcrete, theta: float, point_na: tuple[float, float], ultimate_strain: float, d_n: float) → list[CPGeom] | list[CPGeomConcrete][source]#

Splits geometries at discontinuities in its stress-strain profile.

Parameters:

  • geom (CPGeom | CPGeomConcrete) – Geometry to split

  • theta (float) – Angle (in radians) the neutral axis makes with the horizontal axis (\(-\pi \leq \theta \leq \pi\))

  • point_na (tuple[float, float]) – Point on the neutral axis

  • ultimate_strain (float) – Concrete strain at failure (required for ultimate=True only)

  • d_n (float) – Depth of the neutral axis from the extreme compression fibre (required for ultimate=True only)

Returns:

List of split geometries

Return type:

list[CPGeom] | list[CPGeomConcrete]
