Abstract
In the present study, the effect of adhesion on axisymmetric contact problem for functionally graded material (FGM) coating-substrate system under the spherical indenter is considered. The linear multi-layered model is applied to model the functionally graded coating with arbitrarily varying material properties. The couple effect of adhesion parameter and gradient index is calculated based on the singular integral equation which can be solved by using the numerical method. The results show that the pull-off force, the contact region and the surface stress distribution between the indenter and surface of FGM coating are affected by adhesion parameter, gradient index and coating thickness.

FGM涂层-基材系统的球面粘附接触问题
摘要
在本研究中,考虑了球形压头下功能梯度材料 (FGM) 涂层-基材系统的粘附对轴对称接触问题的影响。线性多层模型用于模拟具有任意变化材料特性的功能梯度涂层。黏附参数和梯度指数的耦合效应是基于奇异积分方程计算的,该方程可以用数值方法求解。结果表明,拉拔力、接触区域和压头与FGM涂层表面的表面应力分布受附着参数、梯度指数和涂层厚度的影响。
