Equation (1.4) was proposed [8] as an extension of the classical D’Alembert wave equation for free vibrations of elastic strings, which took the length of the string produced by transverse vibrations into account. After the pioneer work of Lions [13], where a functional analysis approach was established, Kirchhoff type problems began to attract comprehensive attention of mathematicians. Recently, problem (1.3) has been extensively investigated by many researchers using the variational methods, see for example [3, 6, 7, 12, 19].
