CES EduPack Bulletin, Jan 2012

Hints and Tips

In this edition:

  1. Using favorites to create a custom subset
  2. Tracking the development of new materials using the 'date first used' attribute
  3. Dynamic eco comparisons

1. Using favorites to create a custom subset

Working with advanced (level 3) data, we can use favorites to help explore the impact of strengthening mechanisms on pure Al as follows:

To display a chart, we need to insert a graphical selection stage. Set 'Select from' to ' MaterialUniverse:Metals'. Set the axes to be Fracture toughness vs Yield strength:

Fracture touchness vsYield Strength for Metals in Level 3

To start the comparison, locate ‘Al, commercial purity, 1-0’ in the Browse Tree, and add it to your favorites using the right-click menu:

Add to Favorites

You can quickly visualize where pure aluminum appears on the chart using the 'Show Favorites' button:

Show Favorites (star)

One Favorite...

To visualize the impact of strengthening mechanisms, and to see performance relative to other metals/alloys, add a selection of such materials to your favorites.
Note: Each 'favorite' will now be marked with a star in the browse tree. If you change your mind, there is an option to remove from favorites in the right-click menu.

Once you are happy with the set of materials in your favorite list, you can export the list to share with others:

You can also go on to use the list of favorites as a custom subset:

    First, in the Selection Project, choose 'Select from Custom':

Choose 'Custom' from 'Select From'

    In the resulting 'Custom Subset' window, set the 'Initial subset' to <Favorites>. If you expand the browse tree, you will see that all your favorites (marked with a star) are included :

When using this custom subset, all other materials will be removed from the chart. Materials can be labeled in the normal way by clicking on the ellipse.

When you clear your favorites list, the materials remain in the custom subset. To highlight the original material in your chart, pure aluminum can be made a favorite again. The Show Favorites button will then emphasize the impact of the different strengthening mechanisms with respect to the original material.




2. Tracking the development of new materials using the 'date first used' attribute

Start with a chart of all materials: for example, using all Level 2 Materials, create a new Graph Stage with axes of Young's Modulus against Density, as shown:

All Materials (Level 2)

Making use of the new 'date first used' attribute in CES EduPack 2012, it is now easy to adjust the chart to show only those materials in use within a particular period. For example, to show only those materials in use before 1800 AD, create a new Limit Stage in your Selection Project. Under 'General Properties', set the maximum limit for 'date first used' to be 1800:

Setting the limit to 1800

When this is applied to the graph in stage 1, the modern materials are hidden, revealing only those in use prior to  1800 AD, as shown below.

Materials in use before 1800AD

To show the modern materials greyed out, toggle the 'hide failed records' button. Hide Failed Records

More modern materials can be shown greyed out

By adjusting the limits in stage two, students can quickly explore how new materials have expanded the coverage of material property space over time, and click through to inidivudal datasheets to read more about particular materials.




3. Dynamic eco comparisons

Students want to quickly and easily understand the environmental impact of their design decisions. By using the new Eco Summary Chart, they not only see the energy and CO2 impact broken down across the different life stages, but can compare multiple designs or life scenarios.

For example, we can start with the bill of materials for a water bottle, one of the sample Eco Audit Projects included with CES EduPack.

The sample bill of materials for a water bottle

Use the 'Compare with...' option to open a second bill of materials—this can be a copy of the current product, a new product, or a save product.

As soon as you open the new product, the Eco Summary chart will appear, showing the two materials side by side.  The entries in the key are linked to the 'product name'.
Any adjustments are shown dynamically on the chart. For example, changing the end-of-life from recycle to landfill has the expected impact on EoL potential.

Changes appear dynamcially in the Eco Summary Chart

Students can use this approach to compare multiple products, instantly seeing the impact of every decision. For example, switching to a virgin glass bottle, which is recycled at end of life, has this clear impact: (These graphics were exported using the 'copy' button in the Eco Summary Chart)

To find out more details about the environmental impact of any one of these products, you can turn to the Full Eco Audit Report. These reports can be exported to Word, Excel, or as PDF.
