Viscous MaterialΒΆ

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)


  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.
