Uniaxial relaxation tests on 14 specimens from umbilical fascia were performed. Time dependant mechanical behaviour of human abdominal fascia was modeled applying the non-linear theory proposed by Maxwell-Gurevich-Rabinovich (MGR). The mechanical parameters for relaxed samples of human umbilical fascia were determined and compared according to direction of loading. It was shown that the initial viscosity parameter ∗η and the parameter ∗m, which reflects strain rate influence on stress, vary in wide interval not only among samples from different donors but also between samples from one donor. The detailed time course of the apparent viscosity η(t) and viscous deformation ε(t) was calculated. It was established that the results about viscosity and viscous deformation depend on directions of sample’s loading.
