Prerequisiti

Intermediate knowledge of algebra, mechanics of solids (basic concepts on strain and stress), numerical analysis.

Obiettivi formativi

The objective of the course is to introduce students to classical Computational Mechanics tools, and, in particular, to the most widely used one, namely, the finite element method. The main aim is building a deep knowledge of the basic ideas, the potential, and the limitations of the finite element method, both from the theoretical and the practical point of view, also through the development of simple codes for the simulation of frames and solid mechanics problems.

Programma e contenuti

Review of beam theory and of standard displacement-based methods for planar frames.

Basic concepts of the finite element method and development of a finite element scheme for Bernoulli- Euler beams, starting from the elastica differential equation.

Development of a finite element scheme for (shear-deformable) Timoshenko beams starting from the total potential energy.

Shear locking issues and possible solution techniques.

Review of linear elasticity.

Finite elements for linear elasticity in 1D and 2D.

Development of triangular and isoparametric quadrilateral finite elements.

Numerical integration.

Volumetric locking issues and possible solution techniques.

Review of advanced Computational Mechanics methods.

Metodi didattici

Theoretical lectures at the blackboard will be complemented by tutorials aiming at the practical implementation in Matlab of the methods considered during the lectures.

Modalità verifica apprendimento

Assignments will be handed over and graded during the course. The final examination will consist of a written (closed-book) test. Grading: 40% assignments, 60% final exam.

(The final written test might bu substituted by an oral examination in special situations identified by the teacher).
