Distribution of Stresses and Strains in a Deformed Volume of Metal upon Indentation of a Spherical Indenter
Abstract
Hardness method and method of finite elements are used to study distribution of stresses and strains in the deformed metal under the impression produced by indentation of a spherical indenter with different degree of loading. It is shown that those methods complement each other and their combined use provides more information about the values of stress and strain in different zones of the deformed volume of the metal.
