Vibrations of geomaterials

My PhD research was dedicated to the modelling of stiffness variations in vibrating geomaterials such as rocks or concrete (Figure). In that context, I derived a mathematical model within the framework of continuum thermo-mechanics with internal variables of state. The model follows a phenomenological approach and is qualitatively consistent with experimental observations (see the 2017 Proc. R. Soc. A publication and also the thesis). Computational developments aimed at reproducing experimental results numerically then led to additional publications (3 journal articles, 1-2-3, 2 conference proceedings, 1 book chapter). For these works, I designed and implemented dedicated finite volume schemes to compute nonlinear wave solutions accurately.
