Research Activity
Since the beginning of his academic works, Tornabene developed several structural models for the prediction of the mechanical behaviour of structures with different shapes and materials, taking into account several numerical methods including the classical Finite Element Method (FEM), the Generalized Differential Quadrature (GDQ) method and mesh-free approaches. His scientific production is focused on various research issues, primarily, structural mechanics, smart and innovative materials and computational mechanics should be mentioned. Other research activities include some innovations in the field of fracture mechanics, structural stability and experimental mechanics. Several theoretical models developed by Tornabene are implemented and distributed in the DiQuMASPAB software.
Structural Mechanics
The research activity in the structural mechanics topic is focused on the mechanical analysis of plates and shells made of composite materials, due to their relevant role in civil, mechanical, architectural, aerospace and naval engineering. Shell structures, indeed, show an extraordinary efficiency in bearing the external loads, together with a high degree of resistance, good stiffness and high strength-to-weight ratio. This motivates the large interest of the scientific community since 1940 up to date on doubly-curved shells for many engineering applications.
A shell is a three-dimensional solid that can be studied with the classical theory of elasticity. However, the calculations based on this kind of theory could be computationally burdensome, because of the high number of degrees of freedom involved in the problem. The initial three-dimensional problem can be simplified by a two-dimensional model with the introduction of some proper hypotheses. In addition to the classic theory of elasticity (3D elasticity), several Higher-order Shear Deformation Theories (HSDTs), characterized by different kinematic models, have been developed and analyzed by Tornabene, based on a Carrera Unified Formulation (CUF) setting. Starting from CUF, Tornabene focused his attention on two different approaches to deal with a two-dimensional modeling of anisotropic doubly-curved shells: the Equivalent Single Layer (ESL) and the Layer-Wise (LW). The first approach uses a kinematic expansion of the generalized displacements referred to the shell mid-surface, whereas the second one considers the displacement field on the lower and upper surfaces of each layer within the laminate as primary unknowns. The intermediate kinematic quantities follow the kinematic expansion of the model.
Structures with complex geometries are considered in the works by Tornabene, including singly- and doubly-curved shells and panels, as well as degenerate structures like plates of arbitrary shape and arches. Furthermore, Tornabene studied a general procedure for the structural assessment of arbitrary shapes.
The validity of these models has been proven for the prediction of the static and dynamic behaviour of several structures for different engineering applications. An interesting aspect studied by Tornabene accounts for an efficient post-processing technique to derive the three-dimensional response of structures with a high level of accuracy starting from a computationally efficient two-dimensional approach. This procedure has been verified to provide useful results for different structural design purposes, also focusing on the delamination and fracturing processes in composite materials.
Innovative and Smart Materials
One of the most interesting research aspects developed by Tornabene relies on the investigation of advanced innovative materials, with a particular attention to granular composites like Functionally Graded Materials (FGMs), characterized by a smooth variation of the mechanical properties. In 2009, Tornabene proposed a five-parameter enhanced law to define the through-the-thickness distribution of the FGM volume fraction, including different existing models from literature as subcases. Thanks to his studies, it has been shown that a combined composite material can assume improved dynamic properties with respect to the original constituents, differently from a mere intermediate structural response. Moving from FGMs, Tornabene has also focused on reinforcements with Carbon Nanotubes (CNTs), taking into account the effects of different nanofiber agglomerations.
The development of enhanced materials has always played a key role in Tornabene research. In last recent years, he developed some structural models of laminated structures made of lattice layers, characterized by a typical softcore behaviour. Furthermore, original studies on the so-called Variable Angle Tow (VAT) composites have been improved in order to account for a three-dimensional variation of the material properties within structures, even in presence of different defects and porosities.
Computational Mechanics and Numerical Techniques
Tornabene is known in the scientific academy for his extensive use of advanced numerical methods for the solution of several structural models. More specifically, he adopted the GDQ approach developed by Shu for the solution of several linear and nonlinear problems including the statics, dynamics, and fracture mechanics.
The main issue solved by Tornabene in these studies stems form the possibility to solve differential problems directly in a strong form for structures characterized by an arbitrary shape. More specifically, the Strong Formulation Finite Element Method (SFEM) developed by the author accounts for a decomposition of the physical domain and the direct application of the GDQ numerical technique within each discretized element, mapped in the computational space. This strong form approach differs from classical finite element procedures defined in a weak form. Several practical applications on the static and dynamic behavior of plates, membranes, plane stress and strain states can be found in literature, showing the stability and reliability of this numerical technique, against higher demanding approaches from literature.
Other research topics
The scientific production by Tornabene also accounts for the effect of singularities and inclusions within materials and structures. Above all, he applied several numerical techniques like the GDQ and the Extended Finite Element Method (XFEM) for the study of cracking processes within anisotropic materials. Furthermore, he studied some issues related to the delamination phenomena in composite materials. Above all, he focused his attention on the numerical optimization of some fracture mechanics models with a reduced computational effort, to study heterogeneous materials and standard composite specimens.
Tornabene is currently working on the structural modelling of smart materials, taking into account any possible coupling effect in multifield problems.
Curiosity
Francesco Tornabene is an estimator of J.R.R. Tolkien and of The Lord of the Rings saga. For this reason, he has been named by his students with the nickname “The Lord of the Shells and Beyond” because of his readings and primary research topic. To this purpose, at the beginning of his most important book on shell structures the writes: “One Book for the Lord of the Shells on his differential throne. One Book to rule all the shells, one Book to find them, one Book to bring them and all in the theory bind them. In the land of Shell-wood where the Truth lies”
