The dual variational principle and equilibria for a beam resting on a discontinuous nonlinear elastic foundation
In this paper we study the existence of solutions of the nonlinear fourth-order equation [1] under the asymmetric nonlinear boundary conditions [2], [3] where g is a strictly monotonous function that may have some “one-sided” discontinuities and f and h exhibit some singularities.info:eu-repo/semantics/publishedVersio
