Leartiker acquires a new DMA machine with Fatigue measurement system

Leartiker adds technical singularity within the framework of the characterisation and prediction of the thermo-mechanical behaviour of polymeric materials with the Metravib DMA +2000 machine acquired thanks to the support of the Basque Government's Department of Economic Development, Sustainability and Environment through the AZPITEK 2023 programme.

The DMA +2000 machine developed by the company Metravib, partner of Leartiker since 2019, will be a cutting-edge resource for researchers in the dynamic mechanical analysis of reinforced thermoplastics as it allows measurements over a broader stiffness range and frequency analysis.. In addition, this new machine allows fatigue life measurements using advanced characterisation methods based on crack growth models, a critical behaviour for efficiently predicting the durability of products made with elastomers.

This new machine complements the ‘Vibration and Mechanical Durability Lab’ designed by Leartiker to characterise the dynamic properties and mechanical durability of materials, offering state-of-the-art resources to measure the mechanical response of a wide variety of polymeric materials such as elastomeric materials like rubbers and thermoplastic elastomers, carbon reinforced composites, etc.  The characterisation results obtained in the lab are subsequently used for modelling and predicting the behaviour of components made from these materials.
