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.
