The beam is supported by cubic nonlinear springs to simulate the CNTs resting on an elastic matrix. We obtained the equations of motion for the nonlinear beam using Newton’s 2nd law with Euler’s angle transformation and Taylor series expansion. The frequency in each vibration mode of a SWCNT and MWCNTs resting on a nonlinear elastic matrix was analyzed by using the method of multiple scales (MOMS)
