- Knowledge of the Finite Element Method for linear static and dynamic analysis of structures. Knowledge of problems connected to implementation of numerical codes for solving structural systems by the Finite Element Method.
- Prerequisites
- In order to be able to understand and apply the majority of the techniques described within the Course, the following knowledge is recommended:
Maths: derivation and integration techniques for one-dimensional and bi-dimensional functions; differential equations.
Physics and Meccanica Razionale: vector calculus; equilibrium equation both for static and dynamic problems.
Structural Mechanics and Strength of Materials: equilibrium, compatibility and constitutive equations for the elastic continuum; beam elastic deflection equations.
Non-linear mechanics and structural dynamics: plane problems (plane stress and plane strain problems); equilibrium equation for discrete systems (multi degree fo freedom - MDOF); modal analysis and modal superposition technique. - Teaching methods
- Face-to-face both theoretical and practical classes.
- Other information
- Attendance to classes: optional but strongly advised.
- Learning verification modality
