摘要
在考虑转动梯度效应的基础上 ,对界面附近的应力状态进行了研究 .首先应用摄动法求解了基于偶应力理论的准轴对称问题 ,并在此基础上分析了界面问题和边界约束效应 .结果表明 ,在剪应力作用下 ,在界面附近和固定边界附近存在一组边界效应解 .相对于经典的弹性理论结果 ,它对剪应力有可观的修正 .
The state of stress near an interface is studied taking the effects of rotation gradients into account. Firstly, the quasi axis symmetry problem is analyzed by means of the couple stress theory and the perturbation method. Then the interface problem and the effects of boundary constraints are investigated. The results show that under shear stresses there are a group of boundary layer solutions near the interface or the fixed boundary. There exist significant adjustments in the shear stress as compared to the classical results.
