This command is used to construct an elastic perfectly-plastic gap uniaxial material object.
uniaxialMaterial ElasticPPGap $matTag $E $Fy $gap <$eta> <damage>
$matTag |
unique material object integer tag |
$E |
tangent stiffness |
$Fy |
stress or force at which material reaches plastic state |
$gap |
initial gap (strain or deformation) |
$eta |
hardening ratio (=Eh/E), which can be negative |
damage |
a switch to accumulate damage in the material. If damage is omitted, default value, the gap material "re-centers" on load reversal. |
NOTE: To create a compression-only gap element, NEGATIVE values need to be specified for $Fy and $gap.
