An enhanced Euler-Bernoulli nanobeam model is presented. The coupled nonlocal model depends on two nonlocal parameters and is obtained by using a suitable definition of the free energy. As special cases, nanobeam formulations based on the Eringen nonlocal elasticity theory and on the gradient elastic model can be recovered from the proposed coupled model. A closed-form solution and a numerical example are presented to illustrate the versatility and efficiency of the proposed nonlocal model
