Determination of the Elastic Characteristics of Bodies with Thin Coatings

Abstract:

We Consider a Layered Elastic Body, Consisting of Base Material with Young's Modulus E0 and Poisson's Ratio ν0 and Coating Thickness δ, Respectively, with E1 и ν1. the Thickness of the Base Is much Greater than the Thickness of the Coating. A Stiffness Model of the Layered Body with Loading His Axisymmetric Load, which Allows to Determine its Elastic Characteristics Is Proposed. the Quantitative Effect of the Relative Thickness of the Coating, the Ratio of the Elastic Properties of the Materials and Forms of the Applied Load Is Shown. an Expression for Determining the Elastic Modulus of the Coating when the Effective Modulus of Elasticity of the Layered Body Indentation Determined by the Method of Oliver-Farr Is Got. the Thickness of a Covering and Elastic Constants of the Main Material and Intentor Are Thus Considered.
