Profile

Cristian graduated in 2008 from the University of Parma (Italy) and got his BSc in Civil Engineering “magna cum laude”.

He continued his education at the University of Parma, where in 2011 obtained his MSc in Structural and Civil Engineering “magna cum laude”.

After the graduation, Cristian worked at the University of Parma because winner of a 10 months scholarship as a member of a university research team, whose main goal was to implement a scientific method for design and optimization of flexible road pavements reinforced with synthetic interlayers.

Moreover he had the possibility to work on many other subjects such as:

  • seismic assessment of masonry buildings
  • structural integrity assessment of metallic components under multiaxial fatigue

In January 2013 Cristian joined The University of Sheffield, starting a PhD focused on the development of a new FE method based on the combined use of the Gradient Mechanics and the Theory of Critical Distances.

(Full Text)., Abstract: In this paper, the accuracy of gradient elasticity in estimating the fatigue strength of engineering components, characterised by the presence of stress risers and subjected to multiaxial high-cycle fatigue loadings, is assessed. In particular, a new approach, based on the combination of the Ru-...

(Full Text)., Abstract: In this paper a unified FE methodology based on gradient-elasticity is presented, including Gauss integration rules and error estimation. Applying the proposed methodology to classical elasticity problems, it has been found that, the linear elements show a convergence rate higher than the...
