Abstract: 

With regard to daily developments in technology, application of carbon nano tubes (CNTs) in manufacturing of many devices and equipment is widely promoted. Many sensors, nanomachines, and developments in oil, petrochemical and aerospace technologies are some of CNTs applications.
Considering the importance and wide range of these applications, recognition and investigation of CNTs behavior is extremely significant. CNTs have a slight natural curvature, hence they are predominantly subjected to different transverse loads. In this research, based on nonlocal elasticity theory, possibility of snap-through and bifurcation behaviors of arch shaped CNTs due to sinusoidal load distribution and on elastic foundation are investigated and corresponding graphs are plotted. To obtain buckling critical loads, essential stability equations are derived. Finally, the results of classic theory are compared with the results of nonlocal theory and it is indicated that the dimensionless scale parameter (
l), has a key effect on possibility of buckling and its type occurring. According to the results and plotted graphs, in most cases, increase in dimensionless scale parameter (l) has led to increasing the possibility of bifurcation phenomena; some other cases helped to transition from snap-through to bifurcation, meaning that the possibility of the snap-through phenomena happening has been reduced.
