Research Activities

The research activity aimed mainly to investigate the structural behavior of composite doubly-curved shells, focusing the attention also to the innovations in the industrial processes for the development of new classes of materials. All the considered theoretical models have been validated by means of numerical applications based on the differential quadrature method. These topics can be included in the macro categories, presented in detail in the following.

Structural Mechanics

The research activity in the structural mechanics topic has focused mainly on the analysis of plates and shells made of composite materials. Shell structures occupy an important role in civil, mechanical, architectural, aerospace and naval engineering. The wide use of shells in engineering is due to several advantages. These structures show an extraordinary efficiency in bearing with external loads, a high degree of resistance, good stiffness and a high strength-to-weight ratio. For these reasons, doubly-curved shells have been the main topic of several researches from 1940 up to date.

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, since these models require a huge number of degrees of freedom. The initial three-dimensional problem is reduced to a two-dimensional one defined on the middle surface of the structure through the introduction of appropriate 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. The theoretical framework on which these theories are based is given by the so-called Carrera Unified Formulation (CUF). The formulation in hand has allowed the study and the consequent implementation in a computational code of two different approaches to deal with composite 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 middle surface; the second one, instead, considers the displacements on the lower and upper surfaces of each layer that composes the laminate as main degrees of freedom, whereas the intermediate displacements represent the kinematic expansion of the model. It is important to remind that the CUF includes also most of the classical theories, such as the Classical Shell Theories (CSTs) and the First-order Shear Deformation Theories (FSDTs). Examples of these approaches are the Kirchhoff-Love and Reissner-Mindlin theories, respectively.

The geometries under investigation includes doubly-curved shells and panels (shells of revolution and shells of translations), singly-curved shells (conical, cylindrical and spherical shells), and degenerate shells (circular and rectangular plates). By means of the differential geometry, it has been possible to evaluate all the geometric parameters involved in the governing equations of the considered structures. In the more general circumstance of arbitrarily-shaped shells, the coefficients at issues, such as the main radii of curvature, have been defined in a principal and orthogonal curvilinear coordinate system. In addition, free-form shells and panels have been investigated. Their peculiar shapes have been mathematically defined by means of the so-called Bézier curves.

The structural theories that describe the mechanical behavior of a singly-curved shell of translation are used also to deduce the corresponding higher-order theories for planar beams with curvilinear axis made of composite materials. The Carrera Unified Formulation still represents the theoretical framework of the theories at issue. Nevertheless, the expansion along the width coordinate has been neglected in order to analyze arches and beams characterized by variable cross-sections and curvatures.

The validity of these models has been proven by many numerical applications, in terms of dynamic and static behavior. In particular, a posteriory stress and strain recovery procedure has been developed for the static analysis. This procedure has allowed to obtain useful results for the structural design, by using the three-dimensional elasticity equations. This aims at avoiding the delamination, an issue that typically affects laminated composites. All the results have been accomplished by means of a MATLAB code and can be easily obtained again. The comparison with the values obtained by some commercial codes, such as Ansys, Nastran, Abaqus, Femap, VisualNastran Desktop, Pro\Engineer and Straus, has allowed to prove the validity of the considered structural models.
