| Abstract Scope |
Profilometry-based indentation plastometry (PIP) is gaining popularity as a novel technique for estimating tensile behavior in metals, with smaller sample requirements, simpler preparation, and shorter test times making it attractive for high-throughput testing as well as site-specific evaluation of functionally graded materials. While PIP typically estimates quasi-static properties, the present work aims to extend the technique to capture strain rate sensitivity in low-carbon steel using a full-factorial matrix of indentation parameters (5 speeds, 4 depths) in a dedicated PIP system. The findings were compared against conventional tensile tests on the same material with the goal of establishing an empirical relationship between tensile deformation rates and PIP parameters. These indentation parameters were also replicated in an electromechanical load frame to validate transferability between indenting apparatuses. Once validated, ex-situ indentation enables deformation speeds which exceed the PIP system’s limitations, allowing for further examination of strain rate effects. |
