Learning objectives
The course presents the fundamental characteristics of an analytical procedure that is increasingly used in mechanical design. The objective is to enable students to appreciate the potential and limits of the method, applying it to practical cases.
Prerequisites
Principles and methods of mechanical structural design, machine construction.
Course unit content
Matrix notation and matrix operations, notions of continuum mechanics, the principle of virtual work; reticular plane structures; the compilation of the rigidity matrix for post and structure; the girder; exact solution, approximated solution, transformation matrix, frames; two-dimensional elements in plane tension, plane stress and axial-symmetrical stress: rectangular and triangular elements, isoparametric finite elements, numerical integration, linear elasticity, discretisation criteria, limit conditions, assembly and solution, analysis of results
Bibliography
Supplied during the course.
Teaching methods
The examination consists of a written test and the presentation and discussion of a technical report involving the application of the finite elements method to a real-life problem. Practical work will be conducted in the laboratory, gradually enabling students to learn the use of professional finite elements codes and their application to a series of practical examples.
