This Letter presents an analytical formulation for predicting the radial breathing mode (RBM) frequency of boron nitride nanotubes (BNNTs) with arbitrary chirality. Accurate material properties of the BNNTs are usually not available and the values of the material properties have certain amount of scatter, and some level of uncertainty. In the present investigation, the convex modelling is utilised to consider the bounded uncertain material properties in calculating the RBM frequency of the BNNTs. The results are compared with available data in the literature. Present study may provide useful information on the RBM frequency of the BNNTs with arbitrary chirality in practical applications.
