The nonlinear flexural vibrations of micro-and nanobeams in presence of surface effects are studied within the framework of Euler-Bernoulli beam theory including the von Kรกrmรกn geometric nonlinearity. Exact solution is obtained for the natural frequencies of a simply-supported nanobeam in terms of t
