Sustainable Development Goals

Learning Goals

In terms of prerequisites, students should have knowledge of Applied Mechanics, Mathematical Analysis and Linear Algebra.
The objective of this course is to provide students with knowledge of:
Classical Mechanics of Solids
One-dimensional problems
Resultant Diagrams
Plane and three-dimensional bending
Torsion and combination of forces
Notions of circular plate bending
The student should be able to solve, in a balanced and rational way, problems of mechanics of materials.
It should be able to consult bibliography in an organized way and identify a-priori the subject so that it can solve problems of greater complexity.

Contents

1) Strain tensor, compatibility equations.
2) Stress tensor, equilibrium equations, Cauchy's lemma.
3) Generalized Hooke's Law.
4) Longitudinally loaded members.
5) Bending: normal stresses and shear stresses. Displacement equation. Integration methods.
6) Torsion of circular sections, torsion of open and closed thin-walled profiles.
7) Introduction to the Kirchhoff-Love theory applied to circular plates.
8) Structural stability. Introduction to Euler's Theory.
9) Energy theorems.
