IMPETUS - efficient dynamic testing

4a engineering GmbH Hall: TXNA Stand: 11048
Our testing system IMPETUS® enables the mechanical characterization of dynamically
loaded test specimens or components at high strain rates. One essential benefit is the
efficiency in determining material data compared to the state of art.
We enable our customers to test a variety of materials (plastics, composites, foams, aluminum
...) with methods such as bending, dynamic tensile or puncture tests on a single
machine, whilst giving the freedom to customize any testing setup.
Validating the material data is also being made confidently easy with our VALIMAT® software,
where a single click leads to your desired material card.

Key features of our IMPETUS® testing system
No additional drive technology required – purely mechanical operation
 Compact design – fi ts on a standard lab bench
 Integrated safety concept – suitable for lab environments
 Automated data evaluation – in combination with VALIMAT® software
 Realistic loading conditions – e.g., bending tests on actual component sections
 Dynamic high and lower temperature tests from -40 °C up to +120 °C can be performed
in combination with a temperature magazine
 Full DIC integration with automated evaluation

Our stand-alone software VALIMAT® combines test- and model data into an efficient database
format for material characterization. All testing devices are supported and data can
be used to optimize a huge variety of complex material models in LS-Dyna, Pam-Crash,
Abaqus with our fully automated AutoFit process. The material model can then be validated
on simple FEM coupon tests or even custom built-up geometries and load-cases.
