摘要: This paper deals with a class of nonlinear viscoelastic wave equation with damping and source terms
utt - △u - △ut - △utt + ∫0tg(t - s)△u(s)ds + ut|ut|m-2=u|u|p-2
with acoustic boundary conditions. Under some appropriate assumption on relaxation function g and the initial data, we prove that the solution blows up in finite time if the positive initial energy satisfies a suitable condition.
