SteelProfile#

class concreteproperties.stress_strain_profile.SteelProfile(strains: list[float], stresses: list[float], yield_strength: float, elastic_modulus: float, fracture_strain: float)[source]#

Bases: StressStrainProfile

Abstract class for a steel stress-strain profile.

Parameters:

strains (list[float]) – List of strains (must be increasing or at least equal to last)
stresses (list[float]) – List of stresses
yield_strength (float) – Steel yield strength
elastic_modulus (float) – Steel elastic modulus
fracture_strain (float) – Steel fracture strain

Methods

`get_compressive_strength`	Returns the most positive stress.
`get_elastic_modulus`	Returns the elastic modulus of the stress-strain profile.
`get_stress`	Returns a stress given a strain.
`get_tensile_strength`	Returns the most negative stress.
`get_ultimate_compressive_strain`	Returns the largest compressive strain.
`get_ultimate_tensile_strain`	Returns the largest tensile strain.
`get_unique_strains`	Returns an ordered list of unique strains.
`get_yield_strength`	Returns the yield strength of the stress-strain profile.
`plot_stress_strain`	Plots the stress-strain profile.
`print_properties`	Prints the stress-strain profile properties to the terminal.
