Dynamic Characterization
Dynamic testing is one of the most complex topics when dealing with material characterization. Inertial effects and variable strain rates appear together with other general issues like heterogeneous strain fields. This complexity, next to the importance of these characterizations for the crashworthiness applications, have pushed us to develop specific measurement and analysis tools.

High-quality experimental measurements
We count on the most suitable testing techniques for this type of testing, including servo-hydraulic machines, high-speed video cameras and deformation measurement by digital image correlation (DIC) methods. To this we add our own tooling designs to obtain the best possible measurements under dynamic conditions.

Special analysis methods
We use our own specifically defined analysis methods to tailor test results to simulation needs as well as our clients’ preferences. Among other methods, we use 3D surfaces (stress – strain – strain rate) adjusting the dynamic tests in order to consider the strain rate variations that occur locally in the experiments.

Focus on simulation applications
All our testing and analysis methodology is focused on obtaining the best possible descriptions of the materials for the most common dynamic simulation codes.
We advise our clients in the definition of their characterization projects and we provide them with validated material cards that they can introduce directly into their models.

Damage, failure and triaxiality
Nowadays the prediction of the damage and failure of the materials is one of the great challenges of computer simulation. At Newgentechs we work with some of the most advanced failure criteria, including dependencies such as strain rate, manufacturing processes or triaxiality (behavior dependence on the load state, such as tensile, compression, shear, …)
