Downscaling - Specimen tension, load application into smallest specimen Positioning aspect of specimen into force flow is more coarse Increased variation of results typical metall specimen 10 mm positioning accuracy in load axis/diagonal pull > 0,5mm e.g. bond- wire 30 µm positioning accuracy in load axis/diagonal pull > 1,5µm ? manually not possible New strategies to ease handling for load conformity More tests for statistics efforts, costs Handling for specimen arrangement in load axis free of backlash Load noise due to vibrations ratio of load range and dead weight of sensors...

Downscaling Effective use of measurement range at least 1/10 power less, 10.000 • digits useable Resolution of position measurement system sufficient increments, digital signals – high costs for precise systems • (accuracy < 1 µm, resolution < 0.005 µm, range > 10 mm) Possibilities of indirect position measurement limited–hystereses effects at high speed System stiffness and hystereses to correct positioning system Enhanced stiffness for dynamic tests and for fracture toughness low stifness = high energy storage stiffness has to be reproducible for correction calculations •...
