Dynamic small sample testing
DyMaLab has designed and developed static test infrastructure for tensile and compressive testing of purpose-designed miniaturized samples. The home-grown small sample test setups include a bespoke small-scale Hopkinson bar for dynamic experiments
The DyMaLab setups, skills and competencies in small sample testing can be applied for e.g.
- Characterization of heterogeneous properties of welds and functionally graded materials
- Characterization of lab samples produced by severe plastic deformation
- Characterization of mechanical properties of thin films and coatings
In-situ observation of deforming samples in microscopes
Technical Specifications
- Bespoke small-scale Hopkinson bar setup for dynamic small sample testing
- Strain rates in tension and compression up to 1000 s-1
- Digital Image Correlation to capture local strain fields
- Two 5 Mpxl cameras for full-field sample deformation measurements
