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.
