Materials like toothpaste, mayonnaise, cement and mud are not commonly thought of as fluids by most of us. However, in the realm of materials science, these materials are called ‘yield-stress fluids’: they ‘flow’ only if a large enough shear stress is exerted on them, causing them to yield to it and start moving rather than simply deforming elastically.

Understanding yield-stress fluids is important in conventional sectors, such as food processing and construction, and is growing as related to new technologies, such as 3D printing.


Establish YIELDGAP, the EU educational, reserch, and industrial network for yield-stress materials.

Traintwelve (12) ESRs in advanced techniques that will enable a step change in real-world YSM flow characterization and prediction, and to equip them with the right skills and networks required for implementing and developingg these methods further in academia, industrial research adnd consultancy sectors.



Develop significantly improved protocols and algorithms for characterizing the rheological response of real-world yield-stress materials and clarify how the properties can be matched with models.

Evaluate multidisciplinary strategics to measure, control and predict YSM flow in industrial settings.



Derive constitutive laws that account for the micro-. meso- and macroscopic response of the YSMs and determine their material functions under steady, dynamic, shear and extensional prototype and complex flows.

Advance the state-of-the-art computational algorithms and tools to be suited for real-world applications, and introduce the advanced algorithms in existing-source or commercial Computational Fluid Dynamic (CFD) packages adopted by the industrial partners for the process design and control.



Disseminate cutting-edge knowledge, models and tools on YSM flow prediction and control to academic and industrial pertners the general public.
