Bending Analysis of a Boron Nitride Nanotube Cantilever Beam Based on Modified Couple Stress Theory

There are difficulties in determining the properties of nano-sized materials such as bending, buckling and vibration with classical elasticity theories. For this reason, researchers have developed many theories that include the size effects of micro- and nano-sized structures. In this study, the bending equations of a boron nitride nanotube cantilever nanobeam under different loadings are obtained according to the modified couple stress theory and Euler-Bernoulli beam theory and the results are compared.
