I pursue my research with a multi- and inter-disciplinary approach, spanning several application areas of structural mechanics and physics..., usually developing home-made codes.
I investigated various nonlinear aspects concerning non-standard Finite Element formulations, unconventional numerical strategies for nonlinear problems, and multiscale modeling and simulation.
I also developed equivalent constitutive models and ad-hoc numerical schemes for analyzing nonlinear phenomena of nano- and micro-structured materials.
I hold academic rank since 2005 at Roma Tre University. I earned my Ph.D. at Calabria University, while my post-doc was at HUT.

We're collecting on a unique website "Incourant" C++ coding experiences we developed for several research projects.
Some collaborations on the mechanical analysis of graphene nanosheets is being explored through enhanced numerical approaches. Honeycomb metamaterials and their stop-band propagation properties are also being investigated. Read below ongoing works.

Enhanced pseudo-arclength pathfollowing schemes for generally nondifferentiable multi-dof dynamic systems.
We recently released the 2nd version of the C++ code at
Zenodo 
This project is a collection of physics simulation softwares ranging from solid mechanics to fluid dynamics. We're currently released a Laser Metal Deposition simulator with Lagrangian-Eulerian mechanics, a pseudo-arclength pathfollowing solver for nonlinear frequency response curves (running also on iOS devices), and a dynamic solution scheme for optimal hysteretic-damping design of CNT-nanocomposites.
Incourant project
We're working on a C++ code able to solve milions of variables modeling interatomic actions in single-layer graphene sheets. We aim to predict the nonlinear mechanical response under quasi-static conditions, by exploring enhanced numerical solvers using multilevel and parallel/distributed strategies.

We're investigating both models and numerical strategies for characterizing dynamical properties of honeycomb structures embedding local nonlinear resonators. Our activities (also supported by experimental studies) are tailored to design stop-bands distributions by optimizing lattice geometry.

We're planning to extend the pathfollowing algorithm for running large-scale dynamic problems. We aim at a general-purpose framework able to perform periodic-solutions parameter continuation of nonlinear ODEs, just evaluating the vector field from FE (black-box) spatial discretizations.
