Abstract:The existence and the uniqueness of the local classical solution and the global classical solution for the following initial boundary value problem for a class of damped nonlinear wave equations of fourth order were studied: utt-αuxxtt-uxx+βut+γuxxt=φ(ux)x+ f(u)xx-g(u),x ∈(0,1),t 0,u(0,t)=u(1,t)= 0,t≥0,u(x,0)=u0(x),ut(x,0)=u1(x),x ∈, where α,β0,γ0 were constants,u(x,t) denoted an unknown function,φ(s),f(s) and g(s) were given nonlinear functions,u0(x) and u1(x) were given initial value functions.
Keywords:nonlinear wave equation  initial boundary value problem  global solution
