Modeling and analysis of bi-directional functionally graded nanobeams based on nonlocal strain gradient theory

作者：

Highlights：

• Material properties are simultaneously distributed in two directions.

• A more in-depth study is presented to clearly understand the effect of material parameter and nonlocal parameter.

• The nonlocal strain gradient theory is used to investigate the bending and buckling behaviors of the BDFG nanobeam structure.
