The instrumented indentation tester is an all-in-one test equipment for non-destructively measuring mechanical properties (yield strength, tensile strength, modulus of elasticity, processing hardening index), residual stress, hardness, and fracture toughness using Instrumented Indentation Technique. When the instrumented indentation tester was first developed, it was called by various names such as automated indentation tester, continuous indentation tester, and portable indentation measuring tester, depending on the purpose and method of use, and the integrated name was used for external activities and device promotion.
The instrumented indentation tester was organized and classified according to the measurement properties and cases, and the model name was called “AIS”. “AIS” is an abbreviation of Advanced Indentation System and is a collective term for instrumented indentation tester. Based on the characteristics of each equipment and the measurement properties, it is assigned by dividing it by number or name. (Example, AIS2000 (currently, AIS2100): tensile property measurement model, AIS3000: residual stress measurement model, etc.)
The instrumented indentation tester continuously measures the indentation load applied to the material under test and the corresponding indentation depth, and obtains the indentation load and displacement curve. The obtained data is automatically transferred to a computer connected by wire or wirelessly. Based on this, it is a tester that allows users to analyze the state of materials and create a report through a simple program click procedure and it has been established as KS B 0950, B 0951, ISO/TR29381, KEPIC code MDF A370 and ASME Code case 2703, and its technology is recognized.
