SCIENTIFIC ACTIVITIES
The research activity has developed within the following subjects. The common feature of a combined theoretical /experimental approach since a major objective for our discipline is to develop efficient and accurate methods for mechanical design.
Mechanics of composite materials
The fiber reinforced composite materials are of interest for high-end applications in automotive and aerospace where a high stiffness / weight ratio drives component development. The study focused mainly on the woven composite laminates that have a number of structural and geometric parameters heavily affecting the mechanical behavior.
- Theoretical
A proposed computational approach is based on finite element discretization of the characteristic elementary cell of the specific weave and on the application of appropriate boundary conditions that ensure the periodicity of the displacement and stress fields that characterize the woven composite. According to the constitutive laws for fiber and matrix was then possible to predict the weave-dependent stiffness and strength of the laminate. Detailed stresses and strains in the elementary cell allowed the modeling of damage development
- Experimental
The experimental characterization has focused mainly on carbon fiber reinforced composites both woven and unidirectional. Hybrid carbon / polymer woven composites were also considered. The results as stiffness and tensile strength and in-plane shear made it possible to calibrate the numerical models on a faithful reproduction of the real material at the mesostructural level.
A technique for monitoring the damage based on the electrical resistance change of carbon fibers has been developed. The technique was applied to the study of the development of progressive damage in laminated fabrics by comparing the evolution of the potential drop within a specimen and the voltage response to mechanical deformation and damage .
Fatigue of Materials
Fatigue is one of the physical phenomena of greater importance for the mechanical design for product reliability. The following are the main themes of research in this area.
- Integrated design of engine components made of cast aluminium alloy subjected high temperature fatigue
The increasing competition in the globalized market pushes toward reducing the time resolution of a new engine. This objective is that you think may be achieved by speeding up the design and reducing the number and time of the test bench, thanks to an improved predictive capability achievable using modern simulation tools. An acceleration of the design phase can be achieved with a high integration of skills and support tools such as CAD, FEA and simulation of casting process. These methodological innovations need to be developed into new design procedures to be tested on cases of industrial importance. A multidisciplinary project, with Ferrari company Maranello (MO), a leading global manufacturer of sports cars and high performance engines as main partner was proposed and funded aiming at developing an integrated design methodology of engine components made of cast aluminum alloys subjected to dynamical loads and elevated temperatures. The project entitled "Study, design of mechanical components for high performance and reliability in aluminum alloys stressed in thermomechanical fatigue for engine applications," was developed according to a multi-disciplinary academic participation and was funded under contract HI-MECH FAR. The project lasted 36 months (1/06/2007-31/05/2010) and provided funding for a research activity aimed at acquiring new knowledge for product improvement and a training designed to develop highly specialized skills in this sector.
- Fatigue of aluminium castings
The fatigue behavior of the Al-Si alloy depends in a fundamental way on the microstructure of solidification and, especially, on defects, such as gas pores, shrinkage cavities and oxide film commonly found in the industrial environment. The microstructural characterization of components, such as the die-cast Al-alloy A356 (G-AlSi7Mg0.3) for engine head production was carried out with techniques of optical microscopy and image analysis, to identify the main classes of defects of solidification and to assess any correlations between the size and shape of the same and the SDAS, dependent on the cooling rate, local stress level. The fatigue strength of the material was determined using samples extracted from castings. The rotating bending tests showed high scatter in the relation between stress amplitude and number of cycles to failure. This is due to pore size variation as demonstrated by the observation of fracture surfaces with the scanning electron microscopy and finite element analysis.
