- class StrandProfile(strains, stresses, yield_strength)[source]#
Bases:
StressStrainProfile
Abstract class for a steel strand stress-strain profile.
Implements a piecewise linear stress-strain profile. Positive stresses & strains are compression.
- Parameters
strains (
List
[float
]) – List of strains (must be increasing or equal)stresses (
List
[float
]) – List of stressesyield_strength (
float
) – Strand yield strength
Methods
Returns the most positive stress.
Returns the elastic modulus of the stress-strain profile.
Returns a strain given a stress.
Returns a stress given a strain.
Returns the most negative stress.
Returns the largest compressive strain.
Returns the largest tensile strain.
Returns an ordered list of unique strains.
Returns the yield strength of the stress-strain profile.
Plots the stress-strain profile.
Prints the stress-strain profile properties to the terminal.
