中文摘要：
基于表面弹性力学，利用Boussinesq-Sadowsky位移势函数方法，研究了在剪切作用下，无限大介质中具有变曲率纳米椭球孔洞附近的弹性场．结果表明它们强烈依赖孔洞的大小、形状和表面能．这些特征有助于解释纳米尺度下材料的特殊力学性质．
英文摘要：
Based on surface elasticity theory we considered the effect of interface energy on the elastic fields near a spheroidal nano-cavity embedded in an elastic medium. Using Boussinesq-Sadowsky potential function method, we obtained the deformation field near the cavity subjected to a shear loading at infinity. The results show that the elastic fields near the nano-inclusion depend strongly on the interface properties, the size, shape of inclusion and loadings. These new characteristics may be helpful in understanding various relevant mechanical performances of nanomaterials.
