CES EduPack Bulletin, Jan 2013

Hints and Tips

In this edition:

  1. Video Tutorials (working with graphs in CES EduPack)
  2. Combining searches and graphs to explore the effects of heat treatment (CES EduPack 2013)
  3. Using electrical components in Eco Audits

1. Video Tutorials

Almost 50% of respondents in Granta's recent survey didn't know about the video tutorials... so here's a quick guide. If you open CES EduPack 2012, you'll find them linked off the help menu:

Video Tutorials can be found on the help menu in CES EduPack

When you get your copy of CES EduPack 2013, you'll find the link in the same place. However, to help students get started quickly and find what they need, the videos will all be on YouTube—ready for them to search for and watch when they need them. Tutorials have been cut into bite-sized chunks, and placed in playlists linking related topics. In the preview here, you can watch two short videos on making charts in CES EduPack 2013:

   

2. Combining searches and graphs to explore the effects of heat treatment
(CES EduPack 2013)

The new search engine in CES EduPack makes it even easier for students to find the information they need. This example makes use of both the enhanced search and the new 'Condition' attribute to help students investigate the effects of heat treatment on carbon steels.

Using CES EduPack 2013, open the Materials and Process database at Level 3 by selecting the appropriate image on the new-look start screen:

Choose Level 3 from the start screen

Search for [Annealed NOT (Tempered OR Aged)]. Highlight the results and right click. This will give you the option to turn them all blue, as shown:

Next search for [Normalized NOT (Tempered OR Aged)] and turn all the results lime green. Note the use of the NOT and OR logic operators to return only records which contain the word 'Normalized' but not 'Tempered' or 'Aged'. Opening a datasheet at random confirms this—the search term is highlighted in yellow, having picked up on the new Condition attribute:

Finally, we can search for and recolor another heat treatment condition, 'As rolled', using [As roll*]. Note the use of the wildcard [*] in the search term here.

We could go further and highlight different tempering temperatures in different colors...  but instead we'll turn to making the graph. First, we must define a custom subset of carbon steels:

Plot a a chart of Yield Strength again Carbon content:

Charts like this can help students to quickly explore the effects of the heat treatment, or other properties, demonstrating how:

  • Annealed steels typically have lower yield strength.
  • Lower proportions of carbon typically result in lower yield strength.
  • Higher temperature tempering gives rise to higher yield strength—as becomes clear when different temperatures are colored appropriately/ But we leave that for you and your students to explore...

3. Using electrical components in Eco Audits

The Eco Audit Tool helps to teach key concepts in eco design and aids project work to analyze the environmental impact of products at each of their main life stages. But did you know you can not only input specific materials but also electrical components such as printed circuit boards used in electrical products?

This can be seen using one of the Eco Audit sample files which come with your software. Open the hairdryer project: you'll see that a 'printed circuit board' is included in the bill of materials. To assign such a material, or make changes, simply click on the browse button, as shown here (click to enlarge):

The tool can then be used to assess the carbon footprint and energy. Students can quickly explore the impact of making changes to materials and components in these dynamic summary charts.
