In this article we consider a coupled system of nonlinear Klein-Gordon equations with degenerate damping and source terms. We prove, with positive initial energy, the global nonexistence of solutions by concavity method.

Mathematics Subject Classification (2010): 35L70, 35B40, 93D20.
Keywords: Global nonexistence, degenerate damping, source terms, positive initial energy, concavity method.
