# 4.14.5.25. Viscous Material¶

uniaxialMaterial('Viscous', matTag, C, alpha)

This command is used to construct a uniaxial viscous material object. stress =C(strain-rate)^alpha

 matTag (int) integer tag identifying material C (float) damping coeficient alpha (float) power factor (=1 means linear damping)

Note

1. This material can only be assigned to truss and zeroLength elements.
2. This material can not be combined in parallel/series with other materials. When defined in parallel with other materials it is ignored.
