Bio

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 aspects of both modeling and simulation, concerning non-standard Finite Element formulations, unconventional numerical strategies for nonlinear problems, and multiscale approaches.

I also developed equivalent constitutive models and ad-hoc numerical schemes for analyzing nonlinear phenomena of nano- and micro-structured materials.

Coding

I'm used to code in C++, working with enhanced software libraries and compunting platforms, such as deal.II, FEniCS and Elmer.

Scientific Rank

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.

M. Struct. Eng.

Oct 19, 2000

Master's Degree in Structural Engineering earned at Calabria University with a thesis on "Nonlinear Analysis of brick masonry walls exhibiting damage and friction responses".
Advisor Prof. Raffaele Casciaro.

Key Results

Nonlinear Masonry Mechanics

Both efficient and accurate multilevel strategy solving within mixed formulation brick-by-brick interactions through nonlinear mortar joints, and providing quasi-static carrying-capacity of 2D walls.

CNT-nanocomposite dynamics

Both efficient and accurate meta-heuristic optimization strategy, maximizing damping capacity of polymer-CNT nanocomposites, modeled as 3D continua constitutively nonlinear.

Structural Dynamics Solvers

Both robust and accurate pseudo-arclength pathfollowing schemes carrying out frequency response curves of general non-smooth dynamic systems, excited by time-periodic forcing inputs.

Latest projects

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.

LMD processes

CFD framework coupling multiphase Lagrangian-Eulerian fluid-dynamics for numerical simulation of LMD process in 3D printing. See the C++ code published on

FRCs for nonsmooth dynamics

Enhanced pseudo-arclength pathfollowing schemes for generally nondifferentiable multi-dof dynamic systems. We recently released the 2nd version of the C++ code at

Incourant

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.

Current Works

Graphene Nanosheets

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.

Honeycomb Metamaterials

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.

Pathfollowing Solvers

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.
