Name	Type	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"
