Course objectives
Getting the student familiar with some of the mechanical (materials strength) and thermal features and properties most relevant to practical applications of materials. Particularly with:
•The systematics of stress and strain calculations for loaded materials
•The different types of breakdown criteria
•Some aspects of the relationship between properties and microstructure
•The meaning and information contained in (binary) phase diagrams
•The relevance of atomic diffusion in solids specially as a mean of phase transformations and as a technique of properties modifications of materials
--Introducing students to the Finite Element Method (F.E.M.) as a tool for predicting the materials' response to various mechanical, thermal,…loadings

It is important to notice that typewritten notes as well as a broad exercise collection will be made available at the beggining of the course.This written stuff is intended to be a main guide for students attending the course.
Competence
•Interpretation of the physical meaning of each of the stress tensor and strain tensor components
•Application of the Hooke's Law for elastic materials and its generalization to plastic materials
•Determination of stresses and strains under bending, twisting, and compression for simple geometries
•Understanding of the physical meaning and application of the various breakdown criteria
•Determination of phase composition and phase quantities from a phase diagram
•Solving unidimensional solid diffusion problems
•Basic usage of the various modules and solvers of a Finite Element Method package
Teaching methodology
Brief explanation of the main concepts of each of the 5 lessons by the Teacher in approximetely 2-hour lectures.
The students, organized in pairs or trios, will work out the problems collection. The problems solving will be presented and discussed in classroom sessions by the authoring students. Orientation and support from the teacher will be provided in the above process, if need be.
Additionally, students will compulsorily, perform various computing tutorials on the Finite Element Method application to multiphysics problems as materials strength, thermal transport, electromagnetic behavior, thermomechanical coupling, buckling, and so on for different materials and geometries.
Students will also take at will a final examination consisting of qualitative questions and numerical problems.
Assessment system
Problem solving activity by students will award a mark up to 6 points.
Tutored FEM simulation marking will be between up to 2 points (the higher mark will involve autonomous solving of FEM cases from students).
The final examination will award up to 2 points.

Recommendations for the study of the subject
Most part of the problems proposed in either materials strength or thermophysics are solved by applying a quite systematic procedure. Consequently, students effort should go into getting procedural skills rather than conceptual deepness. Trying to solve a high number of problems should be a most valuable learning strategy.
Comments
Given the (continuous) coursework-based assessment, course attendence by students is compulsory.
