The concept of functionally graded material (FGM) is currently actively explored in coating design for the purpose of eliminating the mismatch of thermomechanical properties at the interfaces and thus increasing the resistance of coatings to functional failure. In the present paper, three-dimensional elastic deformation of a functionally graded coating/substrate system of finite thickness subjected to mechanical loading is investigated. A comparative study of FGM versus homogeneous coating is conducted to examine the effect of the coating type on stress and displacement fields in the system.
功能梯度材料（FGM）的概念目前在涂层设计中得到了积极探索，目的是消除界面处热机械性能的不匹配，从而提高涂层对功能失效的抵抗力。在本文中，研究了有限厚度的功能梯度涂层/基体系统在机械载荷作用下的三维弹性变形。对功能梯度材料涂层和均质涂层进行了对比研究，以考察涂层类型对系统应力和位移场的影响。
