Fluid-structure interactions of hyperelastic geomembranes

Geomembrane systems are used as rehabilitation measure to improve the durability and energy efficiency of hydraulic structures by mitigating water losses, prevent water-based chemical actions and increase energy efficiency. Although the application of geomembrane liners in pressure waterways is very promising and is poised to gain importance in the next years and decades, research and development are still needed to integrate in the design the concepts of fluid-structure interactions. As geomembranes are flexible structure with no bending rigidity, they can undergo large, reversible deformations. The aim of this evaluate the dynamic response of hyperelastic geomembranes when subject to fluid-structure interactions.
