Contexte et objectifs
Italian university research laboratory specialising in the mechanics of polymer materials.It wanted a multi-purpose system capable of determining macro-mechanical criteria under different stress conditions (tension/compression and fatigue) on samples and structures.
Requirement
- Improving understanding of deformation mechanics.
- Measurement of deformations on polymer materials (samples and structures). Determination of poisson's ratio and Young's modulus, measurement of volume deformation.
- Detection, monitoring and measurement of crack advance in fatigue.
Constraints
- Accuracy of the order of a micron or less according to ISO9513 standard
- Integration with existing equipment: Instron electromechanical machine equipped with Bluehill software and MOOG fatigue machine,
- Data synchronisation: real-time communication of deformations measured by video extensometer to machine software : Bluehill to enable user to have all data perfectly synchronised in a single software package and to facilitate calculations of modulus, Poisson's ratio, deformation at break, etc.
Solution
The FVX version XY, 7Markers and fatigue systems meet these conditions.
