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.
