This article introduces various types of experimental method for rheological characterization for viscoelastic solid materials as well as the analytical methods for stress-relaxation, creep behavior, dynamic mechanical properties, and plastic deformation using a simple phenomenological model. For the purpose, some experimental data of dynamic mechanical spectra, creep compliance and mechanical yielding for a high density polyethylene are exemplified.

Keywords: relaxation strength, stress-relaxation, creep, plastic deformation
