ElasticBilin

This command is used to construct an elastic bilinear uniaxial material object. Unlike all other bilinear materials, the unloading curve follows the loading curve exactly.

uniaxialMaterial ElasticBilin $matTag $EP1 $EP2 $epsP2
        < $EN1 $EN2 $epsN2 >

matTag

integer tag identifying material

EP1

tangent in tension for stains: 0 <= strains <= epsP2

EP2

tangent when material in tension with strains epsP2

epsP2

strain at which material changes tangent in tension.

EN1

optional, default = EP1. tangent in compression for stains: 0 < strains <= epsN2

EN2

optional, default = EP2. tangent in compression with strains < $epsN2

epsN2

optional, default = -epsP2. strain at which material changes tangent in compression.

NOTE:

eps0 can not be controlled. It is always zero.
