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
