2. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION Introduction: The CES4 EduPack The CES4 EduPack contains a complete educational resource toolkit for courses on Material and Process Selection. The main elements are: Professor Mike Ashby’s best-selling textbook ‘Materials Selection in Mechanical Design’: the methodological base A comprehensive set of Powerpoint presentations for lecturers Exercises and solutions for students Handouts for students The CES4 software: for demonstrations, exercises, and projects

3. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION Introduction This presentation focuses on the CES4 Educational software and its unique graded databases of materials and manufacturing processes. Three different levels of information are provided in the databases: The Level 1 package helps to inspire newly-enrolled engineering students with real interest in materials, and encourages exploration of the world of materials. The Level 2 package provides a serious tool with a structured methodology for use in intermediate courses (years 2-4). It assists understanding of the role of materials and processes in design and skill in selecting them. The Level 3 package provides senior year and graduate students of engineering materials and design with a professional tool: to assist major design and research projects.

49. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION Select The Select view is used to select materials and processes from the database, using the Ashby methodology, described in the text book: ‘Materials Selection in Mechanical Design’ The selection process involves performing a series of independent selection stages. CES4 keeps track of the results...

50. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION There are three selection tools… Graphical selection will be discussed here. The selection Results window shows the number of materials that have passed all selection stages so far. (All materials currently pass because no stages have been performed.)

51. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION Case Study: Materials for Flywheels Ashby shows that to maximise kinetic energy per unit mass, it is necessary to find the material with the highest value of strength/density, with an adequate fracture toughness and reasonable price. Consider selecting a material for the rotor of a high-speed flywheel... Perform two materials selection stages...

52. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION The first selection stage is a chart of Elastic Limit (strength) vs Density. Each bubble represents a material. The size of the bubble indicates the range of its properties. Clicking on a bubble adds a label... …double-clicking opens the datasheet.

53. UNLOCK THE POTENTIAL OF MATERIALS INFORMATION

57. A line of gradient = 1 is a contour of constant strength/density ratio. Materials above the line have a high value of strength/density… …they pass the selection and appear in the results list. Materials below the line have low values of strength/density. They fail the selection and are plotted in gray.
