Within the field of solid mechanics, my research aims at an improved understanding of the influence of microstructure and damage on the deformability, the strength and the toughness of both natural and high-performance engineering materials. One important challenge is to address anisotropic, non-linear and possibly unstable responses resulting from microstructural changes in plastically deformed heterogeneous materials. To assist the interpretation of experimental observations, performed at various length scales, I develop original, physically-sound, constitutive models and apply them in computational predictions of the microscopic and macroscopic mechanical response. The fields of application span many engineering disciplines, among which mechanical manufacturing, biomechanics and structural integrity.

Numerical modeling of growth and remodeling in stented arteries
Colin Laville

The project aims to predict the evolution of the radial contraction of stented arteries using a continuum mechanics model, with application to bio-resorbable stent development. The capture of the stress state evolution in the artery wall requires a material model that includes:
- the modeling of the main constituents such as collagen, elastin and smooth muscles ;
- time dependent evolution such as growth and structural remodeling.
Some developed tools are also used to predict fracture in bended stainless steels.
