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. |
