DOI: 10.1007/s00419-019-01620-2
Abstract: In an important class of linear viscoelastic media the stress is the superposition of a Newtonian term and a stress relaxation term. It is assumed that the creep compliance is a Bernstein class function, which… read more here.

DOI: 10.1007/s11043-020-09468-8
Abstract: A constitutive material law for linear viscoelasticity in the time domain is presented. It does not only allow for anisotropic elastic behavior but also for anisotropic (i.e. direction dependent) relaxation response. Under the assumption of thermo–rheological… read more here.

DOI: 10.1016/j.polymertesting.2021.107055
Abstract: Abstract At present, the simulation cannot satisfactorily reproduce the actual vibration behavior of short-fiber reinforced plastics. This is because the required linear-viscoelastic material properties, in particular damping, are often not useable in the desired frequency… read more here.
