No full textIl volume raccoglie i contributi che colleghi, allievi e amici di Giovanni Di Domenico hanno voluto offrirgli in occasione del suo settantesimo compleanno. I saggi ruotano attorno alle questioni su cui si è sviluppata la ricca produzione scientifica e l’attività didattica del festeggiato:
Memoria e dimensione bibliografica; Storia delle biblioteche; Biblioteconomia,
scienze sociali, discipline organizzative; Cultura e funzione sociale della
biblioteca nella realtà contemporanea
A numerical study on the solution of the Cauchy problem in elasticity
No full textThis work deals with the Cauchy problem in two-dimensional linear elasticity. The equations of the prob- lem are discretized through a standard FEM approach and the resulting ill-conditioned discrete problem is solved within the frame of the Tikhonov approach, the choice of the required regularization parameter is accomplished through the Generalized Cross Validation criterion. On this basis a numerical experimen- tation has been performed and the calculated solutions have been used to highlight the sensitivity to the amount of known data, the noise always present in the data, the regularity of boundary conditions and the choice of the regularization parameter. The aim of the numerical study is to implicitly device some guidelines to be used in the solution of this kind of problems
A numerical experience about Discontinuous Galerkin finite elements for elliptic problems
No full textElastoplastic analysis of pressure-sensitive materials by an effective three-dimensional mixed finite element
No full textThis work is focused on the analysis of three-dimensional bodies whose mechanical behavior can be modeled by an elastoplastic pressure-sensitive material description. To this end the yield condition is assessed with respect to a general quadratic function capable to represent both standard surfaces, such as Drucker–Prager surface, or more generic surfaces. For the sake of the efficiency and robustness of the numerical analysis of general-shape solids, an effective mixed tetrahedral finite element is used to perform a step-by-step analysis obtaining the complete equilibrium path and the collapse load. Some numerical results regarding technical problems, such as masonry walls and footing problems, show the effectiveness of the mechanical model and of the numerical strategy
