The influence of surface energy on the elastic compression of nanosphere is addressed through the principle of minimum potential energy. By using the displacement potential approach, the elastic field of nanosphere under diametrical compression is derived analytically. Firstly, surface energy induces a uniform pre-existing hydrostatic compression in the entire nanosphere. More importantly, when the ratio of surface energy density to the radius of sphere is comparable with the elastic modulus, th...
