8.10.4.9.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| YieldStress | IfcPropertySingleValue | IfcPressureMeasure |
A measure of the yield stress (or characteristic 0.2 percent proof stress) of the material. |
|
| UltimateStress | IfcPropertySingleValue | IfcPressureMeasure |
A measure of the ultimate stress of the material. |
|
| UltimateStrain | IfcPropertySingleValue | IfcPositiveRatioMeasure |
A measure of the (engineering) strain at the state of ultimate stress of the material. |
|
| HardeningModule | IfcPropertySingleValue | IfcModulusOfElasticityMeasure |
A measure of the hardening module of the material (slope of stress versus strain curve after yield range). |
|
| ProportionalStress | IfcPropertySingleValue | IfcPressureMeasure |
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 | IfcPropertySingleValue | IfcPositiveRatioMeasure |
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 | IfcPropertyTableValue | IfcNormalisedRatioMeasure/IfcNormalisedRatioMeasure |
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" |
|
| StructuralGrade | IfcPropertySingleValue | IfcLabel |
Classification label to define mechanical properties according to structural grades defined in published standards; designated by numbers, letters, or a combination of both. |
