3.1.5.21. Elastic-Perfectly Plastic Gap Material

This command constructs an elastic-perfectly plastic gap uniaxial material.

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

Argument	Type	Description
$matTag	integer	unique material tag
$E	float	initial stiffness
$Fy	float	yield force
$gap	float	initial gap
$eta	float	optional damping tangent (default 0.0)
damage	string	optional damage flag to enable damage behavior

Example

1. Tcl Code

uniaxialMaterial ElasticPPGap 1 1000.0 10.0 0.01

2. Python Code

ops.uniaxialMaterial('ElasticPPGap', 1, 1000.0, 10.0, 0.01)
