Necessity of common data format for curves of Instrumented Indentation Testing (IIT) and review of independent analysis program tangentGo

Abstract

Instrumented Indentation Testing (IIT) is widely used to test mechanical properties of various kind of materials. However, lack of a common data format of experimental data (curves) makes it difficult to exchange curves between testers and to analyse curves imported from other testers. The author has been developing and testing an independent analysis program named tangentGo for IIT users and faces difficulties in support of many testers, since columns, units and other information are quite different from testers to testers. With a common data format, IIT users can discuss calibration process that can significantly affect the output results.
