Curriculum Vitae (252.2 KB)Pietro Lenarda received his Master's Degree in Mathematics at the University of Florence in 2013 and the PhD in Computational Mechanics at IMT, School for Advanced Studies, Lucca in 1017. After two years of post-doc at the Italian Institute of Technology, Genoa (20187-2019) at the Laboratory for Computational Nanomedicine he became Assistant Professor at IMT, School for Advanced Studies in 2019 in the Multiscale Analysis of Material MUSAM research unit. In 2023 he received the National Habilitation as Associate Professor in Solid and Structural Mechanics. Since december 1 2023 he is Tenure Track Assistant Professor at IMT in Structural Mechanics.
He has been visiting fellow at the Numerical Analysis Dept. at the University of Oxford, UK (2016), at the University of Seville, Spain (2022) and at the University Campus Bio-Medico of Rome (2017 and 2022).
In 2018 he won the award for the best PhD thesis by the group of Mechanics of Materials of the Italian Association of Theoretical and Applied Mechanics.
Pietro Lenarda contributes to the PhD program of the School IMT for the track in Systems Science and Management of Digital Transformation with the courses: Computational Contact and Fracture Mechanics, Advanced Topics of Computational Mechanics, Digital Twins for Health. He supervised four PhD students and has been member of the evaluation committee for the selection of visiting professors, post-doc and PhD students at IMT.
The research of Dr. Pietro Lenarda regards computational methods for the numerical solution of nonlinear coupled phenomena in continuum mechanics, with special applications to biomechanics. Original contributions regarded the following topics relevant for high-fidelity digital twin models:
○ Phase field models for brittle fracture, development of decomposition methods for the energy density function for materials undergoing damage both in tension and in compression (multi-phase field), their implementation in Finite Element softwares, and experimental validation. The investigation of damage in artificial porous materials mimicking bones and damage assessment inside human vertebra after screws fixation.
○ Structure-based nonlinear hyperelastic models coupled with electrophysiology for human organs (Ogden-Holzapfel models) accounting for fiber orientation in the tissue. Ongoing work regards the realization of twin models of the gastrointestinal system unde the project “Exploring a novel 3-D in vivo bioprinting technology inside the gastrointestinal system: perspectives and new frontiers” founded by the Italian National Recovery Plan (colaboration with San Luca Hospital, Lucca; Sigma Ingegneria srl, Lucca; University Campus Bio-Medico, Rome).
○ Finite element formulation and numerical simulation of thermo-rheologically complex behaviour in materials with memory via fractional calculus. Applications regarded the development of digital twin models for materials for renewable energy, such as to viscoelastic polymers used as encapsulant in photovoltaics. Novel FE software has been developed to simulate thermo-hygrochemo-mechanical degradation phenomena in photovoltaics under environmental and accelerated ageing test conditions to predict their long term durability.
○ Development of coupled Lattice-Boltzmann Immersed boundary methods for fluid-structure interaction for the simulation of transport of deformable circulating tumor cells and deformable nanoparticles in 3D microcapillary flows.
