Micro Tensile Testing
From a Single Component to the Finished Report
We support customers throughout the complete micro tensile testing workflow - from component analysis to final interpretation of the results.
Our services include:
- specimen fabrication
- micro tensile testing
- data evaluation
- reporting and discussion of results
Customers may use the complete workflow or select individual services.
Tensile Specimen Fabrication
Reliable micro tensile testing requires highly reproducible specimen quality. The specimen preparation therefore focuses on precise geometry, rotationally symmetric gauge sections, minimized surface damage, high surface quality and reproducible dimensions.
Every specimen is inspected before testing. Detailed technical background regarding reproducibility and geometrical error sensitivity is provided in the Knowledge Base.
Micro Tensile Testing
Specialized gripping and transfer systems allow load-free specimen handling and reproducible axial force introduction during micro tensile testing.
Dedicated mounting systems ensure that specimens are transferred from fabrication to testing without introducing bending, torsion or pre-deformation.
A high-resolution optical measurement system monitors specimen geometry during the test.
Evaluation
Customized evaluation software enables efficient processing of micro tensile test data.
The evaluation workflow supports determination of:
engineering stress-strain curves
true stress-strain curves
yield strength
ultimate tensile strength
uniform elongation
reduction in area
strain hardening behavior
Report
The results are documented in a detailed test report.
Results can be discussed and interpreted according to the specific application and material system.
What Makes Testing at Small Dimensions Critical?
Conventional uniaxial tensile testing is a well-established method for determining mechanical properties of engineering materials. At micro specimen dimensions, several parameters become increasingly critical for data quality.
The most relevant aspects are:
round specimen geometry and reliable cross-sectional area determination
specimen geometry and absence of notches or burrs
reproducible axial loading and minimized bending
situ optical measurement of displacement and diameter
