摘要
An indentation measurement apparatus is retrofittable onto any of a variety of load-applying frames and includes a mount for mounting an indenter of any geometry (for example blunt or sharp). The arrangement is very stiff and mechanical values including Young's modulus, strain hardening exponent, yield strength, and hardness can be obtained from a single load/unload versus displacement test. A wide variety of materials can be tested using the apparatus. An optical probe can measure displacement of the indenter head relative to a sample. A new method of calculating strain hardening directly from load/displacement measurement is presented as is a new method of calculating strain hardening exponent.
