concreteproperties.stress_strain_profile.ConcreteServiceProfile#

class ConcreteServiceProfile(strains, stresses, ultimate_strain)[source]#

Bases: StressStrainProfile

Abstract class for a concrete service stress-strain profile.

Parameters
  • strains (List[float]) – List of strains (must be increasing or equal)
