Description

YieldStress

P_SINGLEVALUE / IfcPressureMeasure

Yield Stress

A measure of the yield stress (or characteristic 0.2 percent proof stress) of the material.

UltimateStress

P_SINGLEVALUE / IfcPressureMeasure

Ultimate Stress

A measure of the ultimate stress of the material.

UltimateStrain

P_SINGLEVALUE / IfcPositiveRatioMeasure

Ultimate Strain

A measure of the (engineering) strain at the state of ultimate stress of the material.

HardeningModule

P_SINGLEVALUE / IfcModulusOfElasticityMeasure

Hardening Module

A measure of the hardening module of the material (slope of stress versus strain curve after yield range).

ProportionalStress

P_SINGLEVALUE / IfcPressureMeasure

Proportional Stress

A measure of the proportional stress of the material. It describes the stress before the first plastic deformation occurs and is commonly measured at a deformation of 0.01%.

PlasticStrain

P_SINGLEVALUE / IfcPositiveRatioMeasure

Plastic Strain

A measure of the permanent displacement, as in slip or twinning, which remains after the stress has been removed. Currently applied to a strain of 0.2% proportional stress of the material.

Relaxations

P_TABLEVALUE / IfcNormalisedRatioMeasure / IfcNormalisedRatioMeasure

Relaxations

Measures of decrease in stress over long time intervals resulting from plastic flow. Different relaxation values for different initial stress levels for a material may be given. It describes the time dependent relative relaxation value for a given initial stress level at constant strain. Relating values are the "RelaxationValue". Related values are the "InitialStress"
