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.
