Four-element model (Burgers-Frenkel model) is a convenient engineering model of viscoelastic behavior because of its relative simplicity and its fundamentally correct representation of the real behavior. However
it has only been used to describe viscoelastic behavior in creep. In this paper
the governing differential equation of the four-element model was solved by using elementary calculus. Consequently
mathematical modeling in creep
stress relaxation and dynamic mechanical behavior is performed. The four-element model widely used to describe creep can now be used to predict the stress relaxation and dynamic mechanical behavior of a viscoelastic material.
