Contact Stress Analysis of the Coating Layer Using Finite Element Method

코팅막층의 접촉응력 해석에 관한 유한요소해석

Thin films and coating technologies are used for an enormous and diverse set of application including mechanical and automotive components. Many of these applications require the various properties which can be used for decreasing wear, friction and cost, and increasing the long life. The relationship between the load and the stress is usually nonlinear. The material is often apt to deform plastically under the low loads. Numerical method may be used for some simple problems of the coating. If the property of coating and base materials are inhomogeneous and the geometry is complex, the numerical method may be recommended. In this paper, the contact normal stress of the coating layer has been solved using finite element method.
