Buckling and vibration analysis nanoplates with imperfections

作者：

Highlights：

• A novel finite strip/finite element formulation is proposed to deal with buckling and vibration of imperfect nanoplates.

• The nonlinear equations are solved by the Kantorovich method.

• The imperfection is modelled either as a thickness variation or as a planarity lackness.

• The imperfection can be both localized and distributed.

• Numerical examples are carried out to show the sensitivity of the results.
