This command is used to construct a multi-linear elastic uniaxial material object. The nonlinear stress-strain relationship is given by a multi-linear curve that is define by a set of points. The behavior is nonlinear but it is elastic. This means that the material loads and unloads along the same curve, and no energy is dissipated.

uniaxialMaterial ElasticMultiLinear $matTag -strain $strainPoints -stress $stressPoints

---

$matTag	integer tag identifying material
$strainPoints	array of strain points along stress-strain curve
$stressPoints	array of stress points along stress-strain curve

EXAMPLES:

uniaxialMaterial ElasticMultiLinear 1 -strain -0.04 -0.02 0.0 0.02 0.04 -stress
