LimitState

class persalys.LimitState(*args)

Create a limit state.

Parameters:

namestr

Name

physicalModelPhysicalModel

Physical model

outputNamestr

Interest variable name

operatorComparisonOperator

Comparison operator against threshold (optional)

thresholdfloat

Threshold value (optional)

Examples

>>> import openturns as ot
>>> import persalys

Create the model:

>>> R = persalys.Input('R', 0., ot.LogNormalMuSigma(300., 30., 0.).getDistribution(), 'Yield strength')
>>> F = persalys.Input('F', 0., ot.Normal(75000., 5000.), 'Traction load')
>>> G = persalys.Output('G', 'deviation')
>>> physicalModel = persalys.SymbolicPhysicalModel('model1', [R, F], [G], ['R-F/(pi_*100.0)'])

Create the limit state:

>>> limitState = persalys.LimitState('ls1', physicalModel, 'G', ot.Less(), 0.)
