N2PNeuber Module#

class NaxToPy.Modules.static.metallic.neuber.N2PNeuber.N2PNeuber[source]#

Bases: object

Class used to obtain stresses using the Neuber method.

Examples

>>> import NaxToPy as n2p
>>> from NaxToPy.Modules.static.metallic import N2PNeuber
>>> model = n2p.load_model(r"file path")
>>> element_list = [(24581218, '0')]
>>> n2pelem = model.get_elements(element_list)
>>> n2plc = model._load_case(68195)
>>> neuber = N2PNeuber()
>>> neuber.Model = model # compulsory input
>>> neuber.Element_list = n2pelem # compulsory input
>>> neuber.LoadCases = n2plc # compulsory input
>>> neuber.calculate() # neuber stress are calculated

Ramberg_Osgood_curve(elements: list[N2PElement])[source]#

Plots the Ramberg-Osgood curves for a given list of elements.

This method generates stress-strain curves for the materials associated with the provided elements.

Parameters:

elements (list[N2PElement]) – A list of elements for which the Ramberg-Osgood curves are to be plotted. Each element is mapped to a material with the required properties (Young’s modulus, yield stress, and Ramberg-Osgood exponent).

Returns:

X-axis: Strain
Y-axis: Stress
A curve for each unique material with a legend displaying:
- E: Young’s modulus
- YS: Yield stress
- n: Ramberg-Osgood exponent
Gridlines, axis labels, and a title for better readability.

Return type:

Plot

calculate() → None[source]#

Executes all necessary calculations as the final step in the workflow.

Returns:: None
