Indentation Behavior of Aluminum Alloy with Inclusions

In this paper Finite Element Method (FEM) was used to study the indentation behavior of aluminum alloy 2Al2 with nonmetallic inclusions. Indentation elastic-plastic tests and indentation creep tests were simulated with a cylindrical indenter to analyze the influence of the inclusion size and the inclusion depth. FEM results indicate that the existence of inclusions will have certain influence on the indentation behavior, and when the inclusion size is close to the indenter size, the influence is obvious. For the indentation method, the conclusions can provide some useful information in the project application.
