An existence result for a system of semilinear beam equations with damping at nonresonance. (Chinese. English summary) Zbl 1028.35112
Summary: This paper deals with the periodic-Dirichlet boundary value problem for the system of semilinear beam equations with damping \(u_{tt}+ u_{xxxx}+ Bu_t= Au+ g(t, x,u)+ h(t,x)\). Using the Lyapunov-Schmidt reduction method together with the Leray-Schauder fixed point theorem existence of a solution for this system under suitable conditions is obtained.
