Abstract

In this paper, analytical solutions of low velocity transverse impact of a nanoparticle on a NANOBEAM are presented by using the nonlocal theory to bring out the effect of the non local behavior on dynamic deflection. Impact of a mass on simply supported and clamped NANOBEAMs are investigated by using non local Euler-Bernoulli beam theory. In order to obtain an analytical result for this problem, an approximate method has been developed wherein the applied impulse is replaced by a suitable boundary condition. A number of numerical examples with analytical solutions for both non local and classic beam have been presented and discussed. The dynamic deflection predicted by the classical theory is always smaller than those predicted by the non local theory due to the non local effects. The inclusion of the non local effect increases the magnitudes of dynamic deflection and decreases frequencies. Furthermore, the mass and the velocity of the nanoparticle (striker) have significant effects on the dynamic behavior of NANOBEAM.
