Dr Matteo Ciantia

Research interests:

Matteo’s research interest is in theoretical soil mechanics, rock mechanics, and environmental geomechanics, as well as in theory of plasticity. His current projects deal with crushable soils, hydro- and chemo-plasticity of soft rocks, and in general in mechanics of materials composed of chemically reacting solids and liquids. The above subjects involve mathematical modelling and model-driven laboratory experiments. In particular to develop coupled constitutive models for soft-rocks and soils innovative approaches to uncouple processes at the laboratory scale are required. In particular, Matteo has developed methodologies to uncouple plastic mechanisms induced by hydro-chemo-mechanical weathering processes and crushing/breakage in soils by means of ad-hoc experimental tests. Matteo is also active in numerical modelling. His expertise includes standard Finite Element formulations and the Discrete Element Method. Matteo he has recently started to use the Particle Finite Element Method to model-driven piles in geomaterials in collaboration with the Barcelona UPC group.
