4.14.3.3. Elastic-Perfectly Plastic Gap MaterialΒΆ
- uniaxialMaterial('ElasticPPGap', matTag, E, Fy, gap, eta=0.0, damage='noDamage')
This command is used to construct an elastic perfectly-plastic gap uniaxial material object.
matTag
(int)integer tag identifying material
E
(float)tangent
Fy
(float)stress or force at which material reaches plastic state
gap
(float)initial gap (strain or deformation)
eta
(float)hardening ratio (=Eh/E), which can be negative
damage
(str)an optional string to specify whether to accumulate damage or not in the material. With the default string,
'noDamage'
the gap material will re-center on load reversal. If the string'damage'
is provided this recentering will not occur and gap will grow.
