![]() Professor Contact Recent publications 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.
