| 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。

| Abstract: | 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 understandi... |
