3.1.5.20. Elastic-Perfectly Plastic Material

This command constructs an elastic-perfectly plastic uniaxial material.

uniaxialMaterial ElasticPP $matTag $E $epsP <$epsN $eps0>

Argument	Type	Description
$matTag	integer	unique material tag
$E	float	tangent stiffness
$epsP	float	strain at which material yields in tension
$epsN	float	optional strain at which material yields in compression (default = -$epsP)
$eps0	float	optional initial strain (default 0.0)

Example

1. Tcl Code

uniaxialMaterial ElasticPP 1 3000.0 0.02

2. Python Code

ops.uniaxialMaterial('ElasticPP', 1, 3000.0, 0.02)
