The true_stress_strain
module¶
Simple conversion functions from technical stress/strain to true stress/strain including fracture stress/strain.
- pylife.materiallaws.true_stress_strain.true_fracture_strain(reduction_area_fracture)[source]¶
Calculation of the true frature strain (in the FKM Non Linear (static assessment)) :param reduction_area_fracture: directly measured on the fractures sample :type reduction_area_fracture: float
- Returns
true_fracture_strain – descrivbes the calculated true fracture strain.
- Return type
- pylife.materiallaws.true_stress_strain.true_fracture_stress(fracture_force, initial_cross_section, reduction_area_fracture)[source]¶
Calculation of the true fracture stress (euqation FKM Non-linear (static assessment))
- Parameters
- Returns
true_fracture_stress – calculated true fracture stress of the sample.
- Return type

Calculation of true strain data (from experimental data generated by tensile experiments)
- Parameters
tech_strain (array-like float) –
- Returns
true_strain
- Return type
array-like float
