The Influences of Residual Surface Stress on the Thermo-elastic Bending of Simply Supported Nanoplates

Z.Q. WANG, Y.P. ZHAO

Abstract


When thickness of plates is in nanoscale, the surface energy effect will become prominent, which renders the effective mechanical behaviors of plates to be size-dependent. In this paper, the classical plate theory is modified, by taking the surface energy effect into account, to investigate the size-dependent thermal bending of simply supported nanoplates. Results show that not only the surface elasticity but also the surface residual stress has significant effects on the thermal bending deformations.
