By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Non-Linear Mechanics. According to news reporting out of Harbin, People's Republic of China, by VerticalNews editors, research stated, "This paper studies the influence of surface energy (Which includes the residual surface stress and surface elasticity) on the postbuckling behavior of nanoplates. The governing equations are derived by using the principle of minimum potential energy."
Our news journalists obtained a quote from the research from Graduate School at Shenzhen, "Galerkin's method is employed to obtain the approximate postbuckling load of the nanoplates. The results show that the influence of surface energy on the postbuckling load of the nanoplates becomes increasingly significant when the thickness of the plate decreases. If the thickness of the nanoplates is larger than 20 nm, the influence of surface energy can be neglected. In addition, for nanoplates whose length to thickness ratio is smaller than 10, neglecting the shear deformation may yield significant error in predicting the postbuckling load."
According to the news editors, the research concluded: "This study may be useful for the stability design of plate-like nanostructures in micro-electromechanical systems (MEMS) and nano-electromechanical systems (NEMS) in nanotechnology."
