摘要
In this paper we consider the wave equation with nonlinear damping and source terms. We are interested in the interaction between the boundary damping -vertical bar y(t)(L, t)vertical bar(m-1)y(t) (L, t) and the interior source vertical bar y(t)vertical bar(p-1)y(t). We find a sufficient condition for obtaining the blow-up solution of the problem. Furthermore, we also obtain that the solution may blow up even if m >= p. (C) 2011 Elsevier Ltd. All rights reserved.
