The subject of Calculation and Design of Automobile Structures constitutes an introduction to the elasticity and strength of materials and their application in the field of automobile design.

The elasticity and strength of materials is the science that studies the behavior of the deformable solid. It can be contextualized within the subjects of Applied Mechanics. When studying solids, two types are distinguished: rigid solid and deformable solid. In this subject, it will be considered that solids are deformable. These elements have a simple geometry, and allow the use of calculation hypotheses.



This subject incorporates fundamental aspects to be considered in the design of automotive structures that are applied to different products, considering aspects related to strength, safety, deformation, type of materials used and price.

GENERAL CFB1 Apply the strategies of the methodology in Engineering: to analyze the problematic situation qualitatively and quantitatively, to propose hypotheses and solutions using the Engineering models in the Automotive area.

RA1 Applies material strength knowledge to simple geometry cases of columns and beams subjected to forces and moments to know the tensile state and related deformations.

TRANSVERSAL CT2 Adopt a responsible, orderly attitude at work and ready to learn considering the challenge of the necessary continuing education.

RA2 Applies the knowledge of strength of materials and structures to solve theoretically presented conceptual issues using specific vocabulary and terminology.

TRANSVERSAL CT3 Ability to solve problems with initiative, decision making, creativity, critical reasoning, leadership and to communicate and transmit knowledge, and skills.

RA3 Correctly expresses in writing, in a graphic and orderly way, the resolution methods, results and aspects inherent to the problem posed by the calculation, and the design of structures using specific vocabulary and terminology.

SPECIFIC FB6 Understanding and mastery of the basic concepts about the general laws of mechanics, and their application for the resolution of problems related to automotive engineering.

RA4 Solve the proposed exercises in class individually in the field of calculation and structure design, properly applying the strategies typical of the scientific methodology: to analyze the problematic situation qualitatively and quantitatively.

SPECIFIC FI5 Knowledge and use of materials strength principles for application to Automotive Engineering.

RA5 Works effectively as a group to solve the proposed exercises to estimate the stress and strain states of simple geometry pieces.

BASIC CB4 Know how to transmit information, ideas, problems and solutions to a specialized and non-specialized audience.

RA6 Works effectively as a group. It seeks information, poses hypotheses and solutions integrating capabilities and knowledge for the design and calculation of a part of the structure. Expose the results to other colleagues.

In the theoretical lectures, the theory will be explained and related examples will be solved.

In classroom practices, theoretical concepts can be explained and exercises to be developed proposed.

In class, the lecturer will propose some works, which can be problems, practices or exercises to work on theory.

During the first part of the subject, the following tasks will be performed:

- Individual and non-presential written exercises

- Group and non-presential written exercises

In the second part of the subject, the following tasks will be performed:

- Presential and non-presential group project calculation and/or design of an automotive structure

- Oral presentation of such project to the rest of the students

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 40
  • Oral defense (%): 5
  • Realization of Practical Work (exercises, cases or problems) (%): 20
  • Individual works (%): 20
  • Team projects (problem solving, project design)) (%): 15

Students who consider this will be able to present their resign of continuous assessment until the ninth week after the beginning of the four-month period, following the procedure described in the regulations and within the period indicated by the regulations of teaching planning and evaluation of the E/A. It will also be communicated to the teacher responsible for the subject. The regulations are in the following link: http://www.ehu.eus/es/web/estudiosdegrado-gradukoikasketak/ebaluaziorako-arautegia



CONTINUOUS ASSESSMENT



Individual and non-presential written exercises. The mark shall correspond to the arithmetic average of the exercises delivered through eGela (if no exercise is delivered in due time, the rating shall be 0). Weighting percentage in relation to the final mark: 20%

Non-presential group written exercises. The mark shall correspond to the arithmetic average of the exercises delivered through eGela (if no exercise is delivered in due time, the rating shall be 0). The mark will be for the group, same for all members. Weighting percentage on final mark: 20%

Individual written tests. Weighting percentage of the final mark: 40%.

Presential and non-presential group project to calculate and/or design a car structure. Weighting percentage of the final mark: 15%.

Oral presentation of this project. Weighting percentage of the final mark: 5%.



Note: it is essential to obtain in each written examination 4.5 points out of 10 in order to apply the percentages described in the continuous assessment. For students who do not get it, if they have done everything else, they will be offered the possibility to do another written exam during the course.



FINAL EVALUATION



Individual written examination. Weighting percentage of the final mark: 40%.



Individual written practical exercise to design and calculate an automotive structure. Weighting percentage of the final mark: 50%.



Oral presentation of this project. Weighting percentage of the final mark:10%.



Note: It is a prerequisite to pass the subject, obtain in each written exam 4.5 points out of 10.

The same as in ordinary call.

Theory and problems explained during lectures.
