The radial breathing mode (RBM) frequency of a chiral single-walled carbon nanotube (SWCNT) under radial, axial, and torsional strain is investigated using a nonlinear stick-spiral model. It is shown that the normalized RBM frequency is strongly dependent on the tube chirality. The normalized RBM frequency of small tubes is also sensitive to the tube diameter, while for large tubes, the effect of tube diameter on the normalized RBM frequency is ignorable. The present findings are helpful to the understanding of strain dependent RBM frequency of a SWCNT.
