This paper is concerned with a class of Kirchhoff models with memory effects u(tt) + alpha Delta(2)u - div(vertical bar del u vertical bar(p-2)del u) - integral(infinity)(0) mu(s)Delta(2)u(t - s)ds - Delta u(t) + f(u) = h, defined in a bounded domain of RN. This non-autonomous equation corresponds to a viscoelastic version of Kirchhoff models arising in dynamics of elastoplastic flows and plate vibrations. Under assumptions that the exponent p and the growth of f(u) are up to the critical range, it turns out that the model corresponds to an autonomous dynamical system in a larger phase space, by adding a component which describes the relative displacement history. Then the existence of a global attractor is granted. Furthermore, in the subcritical case, this global attractor has finite Hausdorff and fractal dimensions.
