YieldStress |
P_SINGLEVALUE / IfcPressureMeasure |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
Yield Stress |
A measure of the yield stress (or characteristic 0.2 percent proof stress) of the material. |
|
UltimateStress |
P_SINGLEVALUE / IfcPressureMeasure |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
Ultimate Stress |
A measure of the ultimate stress of the material. |
|
UltimateStrain |
P_SINGLEVALUE / IfcPositiveRatioMeasure |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
Ultimate Strain |
A measure of the (engineering) strain at the state of ultimate stress of the material. |
|
HardeningModule |
P_SINGLEVALUE / IfcModulusOfElasticityMeasure |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
Hardening Module |
A measure of the hardening module of the material (slope of stress versus strain curve after yield range). |
|
ProportionalStress |
P_SINGLEVALUE / IfcPressureMeasure |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
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 |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
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 |
![](http://www.vfkjsd.cn/ifc/ifc4/img/locale-en.png) |
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" |
