Paper Abstract

THere is an increasing necessity to record the deformation characteristics of microelements due to their increasing demand for engineering applications being used in the automotive industry, micromachines, special sensors etc. The data required are either thermal or mechanical such as Young's moduli, stress-strain values, creep-, fatigue- and fracture data. In this investigation two non-contacting laseroptical strain sensors are being used to determine deformation data in combination with a special designed microtensile machine. The laseroptical strain sensors are applied to determine non-contacting strain values including a laser interferometric system with a high spatial resolution and a laseroptical speckle correlation method with high resolution.
