Abstract: The existence of solution for a fourth-order two-point boundary value problem is studied,where the nonlinear term is a Carathéodory function and contains all lower order derivatives of the unknown function.In mechanics,the problem describes the deflection of an elastic beam simply supported at both ends.

Key words: singular ordinary differential equation, boundary value problem, existence, fixed point theorem
