| We investigate in this paper a value problem related to the following nonlinear higher-order wave equation $$ \eta_{tt}+\left( -\Delta\right) ^{m}\eta-% %TCIMACRO{\dint \limits_{0}^{t}}% %BeginExpansion {\displaystyle\int\limits_{0}^{t}} %EndExpansion g\left( t-s\right) \left( -\Delta\right) ^{m}\eta\left( s\right) ds+\eta_{t}=\left\vert \eta\right\vert ^{p\left( x\right) -2}\eta. $$ Firstly, we prove the existence and uniqueness of the local solution under suitable conditions for the relaxation function $g$ and viable-exponent $p\left( .\right) $, using a method, which is a mixture of the Faedo-Galarkin and Banach fixed point theorem, and prove also the solution blows up in finite time. Finally, we give a two-dimensional numerical example to illustrate the blow-up result. | ||
