Methodologies
Methodologies   ::  
  Description
Problem solving, classroom exercises In the practical work sessions in the classroom, the teacher will guide students in the application of theoretical concepts and results to problem solving, encouraging critical reasoning at all times.
Assignments Exercises will be proposed that students will solve, thus acquiring skill in using the tools necessary to solve problems.
Personal tuition The teacher will resolve the doubts raised by the student individually.
Practicals using information and communication technologies (ICTs) in computer rooms Problems will be solved using software based on the FEM
Laboratory practicals Tensile, bending and torsion tests of bars will be carried out to characterize the behavior of the material.
Lecture The teacher will introduce, through theoretical explanations and illustrative examples, the concepts, results and methods of the subject.

Personalized attention
 
Personal tuition
Description
By prior appointment via e-mail, the teacher will attend to the student, resolving any questions they may have.

Assessment
  Description Qualification
Mixed tests There will be two types of written tests:
1.- Final exam of the entire subject.
2.- Periodic individual work to be carried out by the student 		1.- 80%
2.- 10%
Practical tests 3.- FEM Practices 3.- 10%
 
Other comments and second call

To pass the subject you will have to obtain at least a grade of 3.5 points out of 10 in test 1 in both calls. The subject is passed if the final grade is equal to or greater than 5 points.

In the second call, the results of tests 2 and 3 obtained throughout the semester are valid, although it is not mandatory to have taken them. In the case of not having taken test 2 during the course, the part corresponding to the rest of the subject will have a weight of 90%.
