95771 - Materials Testing and Diagnostics P

Learning outcomes

At the end of the Materials Testing and Diagnostics course, the student knows the techniques for conducting tests on materials and building components, including how to take samples and characterize materials for existing buildings. He is also familiar with the basic elements of European certification of component for buildings and construction, ad well as the quality control.

Course contents

Module 1 of the Materials Testing and Diagnostics course includes an initial theoretical section that will provide the basic knowledge necessary for a complete understanding of the practical tests scheduled for the second part, which will be carried out at the Technical Physics and Acoustics laboratory.

Program

Introduction to Thermodynamics. Units of measurement, zero principle of Thermodynamics, thermometry. Overview of the first and second principles of Thermodynamics for closed systems. Ideal machines and irreversibility of natural phenomena. Open systems and mass and energy balances. Overview of thermodynamic cycles and ideal gases. Mixtures of air and water vapor (atmospheric air) and overview of air conditioning. Overview of heat transfer modes: conduction, convection, and radiation.

Introduction to acoustics. Physical acoustics. dB levels. Frequency analysis. Sound level meters. Free field propagation. Sound absorption, transmission, and insulation. Free field propagation. Acoustics of enclosed spaces. Introduction to lighting technology. Introduction to linear systems and the impulse response of a system, measurement techniques, and applications.

Introduction to the Arduino system for creating low-cost measurement systems. Use of analog and digital temperature sensors, thermocouples, NTCs, PTCs, humidity sensors, pressure sensors, flow sensors, light sensors, and MEMS microphones. Introduction to C++ programming for programming the Arduino board. Small practical experiments in the classroom.

Lecture notes provided by the teacher

Teaching methods

The topics listed in the program will be covered during the lessons. Educational visits and exercises at the Technical Physics and Acoustics Laboratory of the Department of Industrial Engineering.

Assessment methods

Learning is assessed through a final oral exam that verifies the acquisition of the expected knowledge and skills. The oral exam consists of an in-depth discussion with the teacher, which aims to verify the possession of the knowledge and skills that characterize the subject.

Failure to pass the exam may be due to insufficient knowledge of key concepts or a lack of or insufficient ability to understand the physical phenomenon underlying the measurement tests of thermophysical and acoustic properties carried out in laboratory tests.

Students with learning disorders and/or temporary or permanent disabilities: please, contact the office responsible ( https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students ) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.

Teaching tools

Video projector for PC, overhead projector, other aids for online lessons. Course slides will be made available to students.
