This command is used to construct a parallel material object made up of an arbitrary number of previously-constructed UniaxialMaterial objects.

uniaxialMaterial Parallel $matTag $tag1 $tag2 ... <-factors $fact1 $fact2 ...>

$matTag integer tag identifying material
$tag1 $tag2 ... identification tags of materials making up the material model
$fact1 $fact2 ... factors to create a linear combination of the specified materials. Factors can be negative to subtract one material from an other. (optional, default = 1.0)

The parallel material is represented graphically:

In a parallel model, strains are equal and stresses and stiffnesses are additive:

NOTE:

- In addition to strain, the parallel material includes strain rate effects from its component materials.
