3.1.5.23. Elastic Bilinear Material

This command constructs a bilinear elastic uniaxial material. Also accepted as ElasticBilinear.

uniaxialMaterial ElasticBilin $matTag $E1P $E2P $eps2P <$E1N $E2N $eps2N>

Argument	Type	Description
$matTag	integer	unique material tag
$E1P	float	initial stiffness in tension
$E2P	float	secondary stiffness in tension
$eps2P	float	strain at which secondary stiffness begins in tension
$E1N	float	optional initial stiffness in compression
$E2N	float	optional secondary stiffness in compression
$eps2N	float	optional strain at which secondary stiffness begins in compression

Example

1. Tcl Code

uniaxialMaterial ElasticBilin 1 3000.0 300.0 0.01

2. Python Code

ops.uniaxialMaterial('ElasticBilin', 1, 3000.0, 300.0, 0.01)
