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" |
