Learning Objectives
The course will illustrate the physico-chemical and mechanical properties of the main classes of materials and the main industrial technologies for manufacturing. The students will be able to select suitable materials and manufacturing technologies for a specific product and to evaluate the different options as a function of requirements and costs.
Prerequisites
Base knowledge of chemistry, physics and mathematics.
Teaching Methods
Ex-cathedra lessons
Further information
The slides shown at the lessons and other teaching aids are on cd-rom at disposal for copying at Calenzano secretary's office.
Type of Assessment
Written examination (open questions requiring short topic expositions)
