 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. </span></div>
