| Abstract: | We consider the
initial boundary value problem for a class of nonlinear degenerate
wave equations in a bounded domain. By improving the method of
Vitillaro, Li and Tsai, we establish a blow up result for certain
solutions with nonpositive initial energy as well as positive
initial energy. Estimates of the lifespan of solutions are also
given. |

| Keywords: | Blow-up of solution degenerate wave equations positive initial energy |
