This command is used to construct an elastic perfectly-plastic gap uniaxial material object.


uniaxialMaterial ElasticPPGap $matTag $E $Fy $gap <$eta> <damage>

$matTag integer tag identifying material
$E tangent
$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.
