Aim

The aim of the course is to provide a systematic methodology for material and process selection. After the course, the student should be able to make an optimal material choice based on the product's function and set goals with the help of the software Ansys GRANTA EduPack.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to perform a systematic material and process selection based on a methodology including the conception translation, screening and ranking.
• be able to understand and apply the conceptions function, constraints, objectives and free variables during translation of product specific design requirements to parameters related to material.
• optimize the selection process through derivation and formulation of material indices.
• understand and be able to create and use material property charts in correlation to predefined selection criteria.
• formulate condition consisting of multiple constraints and objectives.

Competences and skills
For a passing grade the student must

• be able to perform advanced material and process selection based on the software Ansys GRANTA EduPack.
• be able to critically analyze, estimate and formulate suggestions to durable solutions regarding materials.
• evaluate and develop solutions regarding materials in correlation to the specified design.
• be able to apply knowledge from previous courses.

Judgement and approach
For a passing grade the student must

• have a comprehension of the possibilities and limitations of the specified methodology during material and process selection
• be able to identify and utilize additional knowledge within selected areas of material and process selection.

Contents

Material and process selection is a multidisciplinary field, requiring expertise in solid mechanics, material science, manufacturing methods, and sustainability theory to achieve optimal outcomes. This course is designed to teach a systematic approach to selecting materials and manufacturing methods.

The course utilizes GRANTA software, which includes extensive databases with crucial parameters and properties necessary for making optimized material and method choices. Factors influencing material selection for a product may include sustainability, mechanical loads, chemical environment, temperature, and more. Additionally, the choice of material and product design directly impacts the possible manufacturing methods that can be employed.

In summary, the course content includes:

• Definitions and terminology
• Design and parameter evaluation
• Materials and their properties
• Material property charts (Ashby maps)
• Methods for material and method selection
• Sustainability considerations

The course is structured around a series of lectures that cover the fundamentals of material and method selection. These are complemented by independent assignments and project work. To enhance understanding, seminar exercises are included, where typical examples are explored.
