In this talk I will try to give an introduction to implicit
constitutive theories. In particular, I will focus on strain-limiting
models introduced by Rajagopal, where a nonlinear
relationship is assumed among the linearized strain, strain rate and
the Cauchy stress. I will then talk about a recent joint work with H. A.
Erbay where we investigate traveling wave solutions of a nonlinear
differential equation describing the behaviour
of one-dimensional viscoelastic medium with implicit constitutive
relations. We establish conditions for the existence of such solutions,
and find those solutions explicitly, implicitly, or numerically, for
various forms of the nonlinear constitutive relation. <br></span></p></div>
