چکیده انگلیسی
We investigate the bending behavior of functionally graded (FG) nanobeams with internal porosity and subjected to a hygro-thermo-mechanical loading. The Eringen's Nonlocal Theory (ENT) is here applied for the numerical study, while considering a uniform porosity within the nanobeam. The mechanical and thermal properties of FG materials are assumed to vary throughout the thickness. The equations of motion are derived from the Hamilton's law and solved with the Navier's procedure. A key point of the work is to explore the effect of the material length-scale, power-law index, porosity volume fraction, temperature rise, and moisture concentration on the global deflection of nanobeams, as useful for practical applications.
