Geomaterials under extreme quasi-static loading

Key words: Concrete, Rocks, Triaxial tests, Punch-Through Shear tests, Interfaces, Pore pressure, Mesoscopic modelling.

The analysis of the vulnerability of concrete structures under severe actions requires the characterisation of the mechanical behaviour of concrete under multiaxial stresses. The team therefore aims to characterise the behaviour of concrete under high confinement (axisymmetric triaxial stresses, quasi-oedometric compression) but also to characterise the behaviour of geomaterials and interfaces between different geomaterials in shear (biaxial stresses, Punch-Through Shear (PTS) tests).
