Nanomechanical sensors based on elastically supported double-walled carbon nanotubes

作者：

Highlights：

• Study of elastically supported DWCNTs as nanomechanical sensors is of concern.

• Nonlocal Rayleigh, Timoshenko, and higher-order beam models are employed.

• RKPM is used for the discretization of the unknown fields of the proposed models.

• The role of various factors on frequency shift ratio (FSR) of DWCNTs is examined.

• FSRs of DWCNTs under different boundary conditions are studied in some details.
