Poisson’s ratio structures have been developed for critical protection. In this
paper, the static bending and buckling of FGPR nanoscale beam are studied based
on the nonlocal Timoshenko beam model, in which both Young’s modulus and
Poisson’s ratio are assumed to vary continuously in the thickness direction. By
utilizing total potential energy principle, equilibrium equations are derived.
In the numerical results, beam models with different material properties are
introduced, and the effects of the nonlocal parameter, aspect ratio and the
Poisson’s ratio on the deflection and buckling are discussed.
