Micro Tensile Testing Machine (3)
 

The load framework is a system of springs divided into two parts, which allow to test samples of different thicknesses and diameters at the same force application axle.
The load application of the tensile testing machine is transferred to the clamped sample in a reduced way.

The shape of the micro tensile sample with a cross section of 0,1 x 0,1mm and a length of 0.94 mm in between the markings was optimized using the method of the finite element method.

Using the micro tensile testing, important data like yield point, modulus of elasticity, tensile strength and even displacement as well as breaking elongation can be obtained. Moreover the nonlinear deformation behavior important for a modell concept can be obtained.

First tests on galvanically separated LIGA nickel showed that mechanical properties, like yield point and tensile strength are three times higher than those of conventionally determined, fusion metallurgically manufactured nickel. A suitable thermal treatment eliminates the stack structure of LIGA nickel and influences the mechanical properties. Displacement values, however, are four times lower for LIGA nickel compared to conventionally checked and molten nickel. The thermal treatment also influences the displacement behavior.

Besides tensile tests cyclic tests within the tensile threshold range as well as tests with preservation time are possible.
