When materials are used for structural support, in buildings and general construction, the shape is as fundamental as the material properties themselves. This shape determines how effective the material is fulfilling its structural function, such as beams supporting loads in bending etc. The influence of the shape is usually separated from the visual process of material selection in CES EduPack. However, there exists a data-table of standard structural sections.
This Case study session deals with selection of structural sections and complementary Finite Element simulations. A good material choice is beneficial as input in a simulation where details about the shape can be explored and the free design parameter used in CES EduPack can be determined.
It is obvious that our built environment is of huge direct importance to everybody’s daily life, but it is also contributing some of our most urgent challenges. With a world population of many billions, the impact from construction and maintenance is monumental. Resource extraction and material production as well as heating and other energy use, including transport systems, all have global-scale consequences.
In this case study, we use the CES EduPack 2019 Architecture edition, to show some features to explore and discuss the Built environment. Materials for buildings are investigated and the Eco Audit Life-cycle tool is applied to a house.
This simplified case study can be performed at Level 2 and illustrates how CES EduPack can be used to investigate the performance of a skateboard. The aim is to understand materials for longboards, used for high speeds and slalom competitions. Material options are discussed and compared with existing designs. There is a set of student exercises to accompany this case. An advanced Industrial Case Study of high-performance Longboard design at Level 3 is also available for licensed educators.
For many products, mechanical performance is important and must be considered during their design. For certain applications, it might be possible to find polymers that are competitive, particularly in terms of cost, weight and corrosion resistance. In this Case Study, we look at materials for a lightweight blade of a chainsaw. It includes deriving performance indices for a stiffness-limited design. We also take durability and cost considerations into account and reflect on the materials of a real chainsaw blade in a reality check. There is a set of student exercises to accompany this case.
Strength, or a material’s ability to resist fracture, is a property commonly tailored for specific applications by materials scientists and metallurgists. In metals, this can be altered by changing how dislocations move through the crystal lattice. But how does one go about altering this mechanical property? In this simplified case study, we will go over three different strengthening mechanisms highlighted in the new MS&E Edition Structure Science Notes as well as show how these different mechanisms impact mechanical properties in various aluminium alloys through the Property-Process Profiles. There is a set of student exercises to accompany this case.
CES EduPack has always been excellent for teaching a design-driven approach to materials for engineers and designers. In addition, there are some embedded binary phase diagrams and textbook-style support for materials science in the Science Notes. In the new Materials Science and Engineering (MS&E) edition 2019, however, these parts have been made more visible and are supplemented with features to boost introductory MS&E teaching and learning. In this simplified industrial case study, we look at how to bridge science and engineering by exploring the novel Phase Diagram Tools and MS&E data-tables to facilitate the understanding of stainless steels and Ni-Cr alloys. Both of which are crucial in many everyday products.
This Active-learning Tool Kit includes a set of templates, handouts and exercises with worked solutions to support teaching of the complex subject of Sustainable Development. It is further supported by the CES EduPack Sustainable Development Edition which is helpful but not essential for the implementation of the method. The Tool Kit has eight Main Parts provided as PDF files: Introduction and content, Method, Handouts, assembled Case Studies, Micro-projects, Instructor Experiences, Templates and Check Lists and Information about the CES EduPack Sustainability Database. The Case Studies provide detailed and clear guidelines on how to apply this methodology to variety of sustainability topics (biopolymers, electric vehicles, wind farms, low carbon concrete and others).
Experience suggests that learning is better achieved by discovery for oneself than by passive listening. The CES EduPack Materials Science and Engineering (MSandE) Package is a set of resources that allows students to explore the relationships between Processing, Structure and Properties. They stimulate discovery and pose questions: why does this property change in that way when the material is processed? Why is this other property unchanged? The package includes data for the elements, data for structural, functional and biological materials, for processes for shaping, joining and finishing, tools to aid understanding of phase diagrams and resources that focus explicitly on the process-structure-property relation. This Toolkit contains the following teaching material to accompany the Materials Science and Engineering database.
