• elastic-plastic material models
• parameter identification
• indentation tests
• inverse analysis procedures

Non-destructive indentation tests are more and more frequently employed for the mechanical characterization of structural metals. Three kinds of experimental data sets as inputs to inverse analyses for parameter identification are comparatively examined in this article: (A) indentation curve, namely the relationship between penetration of the indenter tip versus the force applied on it; (B) both this curve and imprint geometry; (C) imprint profile only. The comparisons are based on two different parameter identification procedures.
