Abstract:

This paper studies the finite time blow up of solutions for a initial boundary value problem of a viscoelastic wave equation with the strong damping term and linear weak damping term at high initial energy level. By using the concavity method, we obtain some new sufficient conditions on initial data such that the solution with arbitrarily positive initial energy blows up in finite time.

Key words: wave equation, high initial energy, finite time blow up, viscoelastic term
