Planning and design of industrial components (Module 2)
Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course, students will have acquired the basic knowledge of the mechanics of deformable elastic bodies, with particular reference to the technical theory of beams.
Skills:
The student will be able to perform the design and verification of some simple structural elements, with particular reference to the organs of machines.
Making judgments:
The student will have the tools to critically evaluate the output of a structural software.
Communication skills:
The student must possess the ability to clearly present a technical report on the design of simple structural elements.
Prerequisites
It is essential to have a basic knowledge of calculus, linear algebra and physics.
Course contents summary
The course aims to provide a unified treatment of the main aspects of the mechanical behavior of structures, referring mainly to the linear elastic response.
The first part of the course is devoted to the evaluation of the static schemes and strain in elastic solids under assigned external actions. Structural theories for beams and the evaluation of the load bearing capacity of structures will subsequently be addressed.
Course contents
The topics covered are more specifically as follows.
Basic principles of mechanics. Fundamental equations of statics.
Constraints, Free Body Diagrams, calculation of constraint reactions in variously articulated bodies.
Diagrams of stress characteristics in elongated bodies (slender beams).
Mohr’s graphical representation. Strength criteria for ductile and brittle materials.
Constitutive relations. Linear elastic constitutive relation.
Normal stress. Twist. Simple bending. Shear flow.
Technical theory of beams.
The application aspect is taken care of through the introduction of a large number of solved examples and exercises

Teaching methods
We provide lectures and exercises on the blackboard.
Assessment methods and criteria
The exam is based on a written test and an oral test. In the written test, the student will be asked to solve a few exercises of the same type as those carried out in the classroom during recitation.
