| Popis: | The vibration of two curved nanobeams with coupling radial springs is considered. A nonlocalEuler-Bernoulli curved nanobeam model has been assumed in order to investigate the radial vibration ofthe double-curved-nanobeam-system (DCNBS) embedded in an elastic medium. Natural frequencies forthe DCNBS are obtained by using the Navier Method. Moreover, the effect of the angle of curvature on thenatural frequencies is discussed. Comparison studies are also performed to verify the present formulationand solutions. It is shown that the results are in excellent agreement with the previous studies. Furthermore,it is shown that considering the effects of the curvature decreases the natural frequency of the DCNBS andthat the natural frequency decreases by increasing the small scale coefficient. In addition, the variation ofthe frequency has been investigated based on the stiffness of the springs in a radial direction. |
