Course purpose

The aim of this course is to train each participant in design-oriented materials selection. After the course you shall have acquired appropriate competence for engineering work related to materials selection. The course introduces analytical tools and methods for qualified materials selection towards engineering applications. Principles regarding material design for typical applications are also treated where the importance of different behavior of specific materials and classes of materials are considered with respect to thermal stability, thermal and electrical conductivity, strength, toughness and chemical resistance, etc.

Comment: It is recommended that you read the case studies after the lecture addressing the particular topic, but read the chapter about the basics and theory before the lecture.

Course literature

M.F. Ashby, Materials Selection in Mechanical Design, Elsevier, 4^th edition (Note: there are also earlier or later editions like the 5^th edition, and they are quite similar. The 4^th edition is recommended primarily because it is available as ebook via Chalmers library. The 5^th edition is however the only edition with hard copies available on the market. The book (5^th and 4^th) and ebook (4^th Ed) are available at Chalmers library. Lecture notes are published on Canvas. Introductory guide to Granta EduPack is found on Canvas，and access to the software will be informed by TAs.

 

Course design

Contents

In the course, particular emphasis is placed on the overall understanding of material performance and its evaluation as well as the methodology and working concept for systematic and objective materials selection. Basics regarding definition, development and use of material indices are treated. Methodology for more complex problems is treated including situations where two or more material property demands should be fulfilled at the same time. An important tool treated is the software Granta EduPack.

 

Organisation

The course is organized via lectures of overview character, interactive exercises (supported by tutorial sessions) and a group-based project assignment (supported by consulting events).

 

The situation might change, but for now all lectures and tutorial/consulting sessions will be held physically, and the students are required to attend lectures/tutorials/consulting sessions in the lecture room. 

 

Changes made since the last occasion

The Zoom option will NOT be provided for this year.

 

Learning objectives

After completion of this course, you should be able to:

• Understand the basics of design-oriented materials selection for engineering applications;
• Work with and apply systematic and objective materials selection based on the principles according to Granta EduPack (previously known as CES EduPack);
• Apply the Granta EduPack in materials and process selection;
• Define correct conditions and objectives regarding materials selection;
• Have common background knowledge about material indices for material performance and understand how these indices are constructed;
• Analyze materials selection case studies for which either single or multiple constraints are active;
• Analyze and evaluate the role of geometrical aspects in materials selection;
• Describe the general principles for definition of material properties and the basic physical principles behind these in general sense.

Examination form

There is no final written exam for this course. The examination is based on the combination of assignments, exercises and project work including final oral presentation and written report. The grading is based on the total score of assignments (max 30p), exercises (max 2p), and the project work (max 18p). The grading will be based on following limits:

 

Grade 3 > 40% = 20p
Grade 4 > 60% = 30p
Grade 5 > 80% = 40p

 

Due dates for submitting the exercises are (in general) two days after the relevant tutorial is given. Due dates for submitting the assignments are (in general) two weeks after they are created. Details are available via Assignments on Canvas. Due date for handing the final project report and presentation file is the second day after the final oral presentation, i.e., before the end of 15/12. Mid-term project report needs to be submitted before the end of 20/11.

Project assignment

Below you find a few proposals for project assignments. Each group may also propose their own subject. The proposal must be approved before starting the work.

Oral presentation in seminar form for the whole class

All members of the group are suggested to participate in the oral presentation

 

Work content

• Application analysis (constraints?), definition of function, derivation of material

indices;

• Discussion regarding alternative solutions (e.g. material indices with respect to only

technical merits, technical merits + cost, technical merits + cost + manufacturability,

ecological merits, etc.);

• Presentation of 2-3 alternative solutions/optimization;
• Definition of other critical factors and their assessment.
