Numerical and Experimental Study on Determination Method of Elastoplastic Properties for Indentation Testing
2021
Instrumented indentation testing is a technique for measuring the local mechanical properties of materials, and is expected to be applied to various fields. Although the depth-sensing indentation method is common, recently, the method that can sense the indentation contact area has been marketed, and it allows accurate determination of the applied stress value, which has been a problem in the past. In this study, we discuss the methodology for determining the mechanical properties of elastoplastic materials using the depth-sensing and the area-sensing indentation technique. A numerical study using finite element analysis and experimental verification was presented.
