Obiettivi formativi

This course aims at enabling the students to perform the advanced mechanical design and the integrty assessment of structures and components, according to the most modern procedures.

Extensive training about finite elements modeling (FEM) will be carried out, for enabling the students to predict the structural response within the frameworks of elastoplasticity, dynamics, structural integrity and damage tolerance.

In order to achieve such objective, notions of material mechanics and experimental characterization will be delivered with a pragmatical approach, respectively addressing the latest models of material behavior (static/dynamic plasticity, material damage/failure), and the most recent laboratory procedures for calibrating such models.

The students will assist to laboratory experiments for static and dynamic testing (motor driven and hydraulic testing machines, Hopkinson bar equipment, data acquisition and image analysis); they will then use the experimental data for calibrating selected material models which, then, will be implemented either in the FEM analyses by way of user subroutines or in the postprocessing phase of FEM results by way of simple spreadsheet calculations.

A 3-C.F.U. section of the course will be also oriented at thermal methods for fatigue asessment; this will train the students at acquiring infrared imagery data and at processing data from thermal acquisitions, aimed at determining the fatigue response of components/structures subjected to cyclical loads.
