This case study webinar for academics explores high-temperature candidate materials, in particular nickel- and cobalt-based superalloys and technical ceramics, for aerospace and automotive applications. Inspired by an industrial research conference presentation, we have studied the suitability of ceramic turbine blades as alternatives to metal alloys for aerospace and automotive applications. We describe the selection procedure in detail and compare the result with the currently used Inconel 713 superalloy. We also discuss how environmental and sustainability aspects can be included in this case.
In this Industrial Case Study we take a look at potential materials for lightweighting trains and railway transportation. EduPack is used to investigate different components in order to reduce the weight and environmental impact. A reduction in the unsprung mass, for example, will help to reduce both energy consumption and track damage. Several types are considered, such as high speed, goods and passenger trains as well as both light-metals and composite material substitutes. A comparison with truck-based road transport systems and the use of structural composites is also made. A link to the associated webinar recording can be found here.
The Bioengineering database of CES EduPack offers the possibility to compare and select materials for various medical and biological applications. This is useful both for teaching students and for making materials decisions in the biomedical field. The Eco Audit tool, recently included with the Bioengineering database, also makes it possible to assess and compare different scenarios in terms of materials and end-of-life options.
In this advanced industrial case study, we explore how CES EduPack can be used to discuss aspects of materials and waste in the healthcare sector. Both material selection for performance and clinical requirements as well as environmental consequences of disposable material and waste. To add realism, we visit the external ASM Medical Materials Database™ which contains over 60,000 approved medical devices.
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‚ as 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.
Strength, or a materials 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. This teaching package contains all the associated exercise and project file resources for this case study.
CES EduPack has always been excellent for teaching a design-driven approach to materials for engineers and designers. In the new Materials Science and Engineering (MS&E) edition 2019, more specific features were included to support introductory Materials Science teaching. 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 teaching package contains all the associated exercises, lectures, and project file resources for this case study.
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. This teaching package contains all the associated exercise and project file resources for this case study.
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. This teaching package contains all the associated exercise and project file resources for this case study.
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 appliances, wind farms, low carbon concrete and others).
This package includes all resources connected with the CES EduPack Materials Science and Engineering (MS&E) Edition. This Edition and resources allow students to explore the relationships between Processing, Structure, Performance and Properties. The edition 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 download includes exercises, microprojects, a white paper, a powerpoint lecture, and project files all related to this MS&E edition.
