Learning Goals
As per pre-requisites, students should have acquired proficient knowledge on Applied Mechanics, Mathematical Analysis, Linear Algebra and Analytical Geometry.
The objective of this course is to provide students with knowledge on Solid Mechanics and Materials Resistance. Students shall develop competences to:
- Analyse and understand stress and strain states in a material point;
- Relate stress and strain for isotropic materials;
- To determine the shear and moment diagrams;
- To analyse linear components under torsion, for different cross-sections;
- To analyse uni-dimensional components under bending;
- To apply failure criteria of the material and to dimension structural components;
- To expand this knowledge to transverse isotropic materials;
- To apply acquired knowledge to structures in composite material and/or sandwich panel.

Contents
The course is divided into two modules. The first module introduces the base concepts of Solid Mechanics. The second module applies these base concepts to materials and structures typically used in airborne structures and satellites.
Module 1 (75% of contact time):
1) Stress tensor, equilibrium equations, Cauchy Theorem.
2) Strain tensor, compatibility equations.
3) Generalised Hookes law and its application to isotropic materials.
4) Shear and Moment diagrams.
5) Torsion of linear beams with circular cross-section, open and closed thin wall profiles.
6) Simple and combined bending. Equation of the Elastic curve.
7) Structural stability. Introduction to buckling. Eulers theory.
8) Materials strength. Failure criteria.
Module 2 (25% of contact time):
9) Hookes law applied to transverse isotropic materials.
10) Sandwich panels and composite materials. Elastic behaviour, classic theory and failure criteria.
