文摘
- •
Using shear deformable beams, vibration of magnetically affected CCNWs is studied.
- •
The equations of motion are derived via surface elasticity theory of Gurtin–Murdoch.
- •
A meshfree method is exploited for discretization of deformation fields.
- •
Roles of surface effect and shear deformation on frequencies are fully examined.
- •
The critical electric current, slenderness ratio, and NW's diameter are determined.
