Analysis of Hertz contact stresses for metallic material with carbides
Abstract
Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental prostheses, gear teeth, ball and roller bearings and many other engineering applications. Although the common concepts for studying these problems implies that the analysis is perform taking into account that elastic solids are imperfection free, the real problems, as well as various failure analysis, underline significance in taking into account those imperfections, [1]. Imperfections in metallic materials can be non-metallic inclusions, carbides, pores and other microstructural defects, [1, 2]. This paper describes model of two cylinders in contact made by metallic material with carbides. The Finite Element Analysis (FEA) is performed in order to discuss the influence of position, orientation and dimension of carbides on Hertz stresses for two cylinders in contact. F...ig.1a shows the FEA model developed for calculation the Hertz stress state for two cylinders, and Fig.2 shows the position and dimension of carbides for two of the series of modelled cases.
