Materials for Engineering

Recommended Prerequisites

Introduction to Materials.

Teaching Methods

The theoretical is followed by theoretical and practical classes, where the applications of each types of materials used in the manufacture of various components / systems are presented. After this exhibition, the student has to solve, individually, a test with ten questions, each with five options. The test duration is 15 to 20 minutes and it is corrected before the next class. This methodology allows the student and teacher to understand what or which points of the course are not well understood, and during the first 15 minutes the following class, the most problematic issues are reviewed.

Learning Outcomes

Knowledge of the different materials used in engineering is one of the main specific skills required for an engineer. In order to be able to intervene in the production and processing of materials as in the conception and development of engineering projects, the engineer must have comprehensive knowledge not only about the nature of the different types of materials, but also a precise and quantitative knowledge of the properties of each material. This discipline  aims to provide expertise on structure / properties / processing / performance of various materials, emphasizing the technological and economic aspects that should govern its application in engineering components.
