Abstract:
1. An indentation assembly for nano and micron scale testing comprising: an indentation tip; a tip holder coupled with the indentation tip, the tip holder having a tip holder thermal conductivity and a tip holder coefficient of thermal expansion, and the tip holder includes a tip holder length and a tip holder volume; a tip holder mount coupled with the tip holder, the tip holder mount is configured for coupling with a transducer, the tip holder mount has a mount thermal conductivity greater than or equal to the tip holder thermal conductivity, the tip holder mount has a mount coefficient of thermal expansion greater than or equal to the tip holder coefficient of thermal expansion, and the tip holder mount includes a mount length and a mount volume; and the indentation assembly is configured to throttle heat transfer from the indentation tip to the tip holder mount, and the indentation assembly is configured to minimize expansion and contraction of the indentation assembly according to the thermal conductivity and coefficient of thermal expansion of the tip holder relative to the tip holder mount wherein:
