modelViscoelasticSlab
Model of a viscoelastic material, using fractional derivatives
Extends from Modelica.Mechanics.Translational.Interfaces.PartialCompliantWithRelativeStates (Base model for the compliant connection of two translational 1-dim. shaft flanges where the relative position and relative velocities are used as states).
