Material Database

Use the Material database to select a part material or add, edit, or remove the selected material data.

The data from material database are stored in the XML format in ...Design Data\Design Accelerator\Tables\Materials folder.

1. On the Ribbon, click the Design tab.
2. Start any generator or calculator, for example Bolted Connection.
3. Switch to the Calculation tab.
4. Check the box next to the Material edit field to open Materials dialog box.
5. Click the row with a desired material to select it. You can also edit desired material values. Double-click the edit field, and enter new value.
6. Click OK to confirm the selection and close the Materials dialog box. The selected material is inserted on the Calculation tab together with corresponding values (Modulus of Elasticity, for example).

Add new material

It is possible to add a new material to the database. When you add a new material, we recommend filling in all columns for particular material. It is possible to enter zero value in some columns. However, when you want to include a desired material in a calculation, you need to enter exact values for material parameters that are listed in the Material section on the Calculation tab of a particular generator or calculator. For example, for Spur gears, you need to enter values for Bending Fatigue Limit, contact Fatigue Limit, Modulus of Elasticity, Poisson's Ratio, and Heat Treatment.

For material for spur gears, bevel gears and worm gears, you also need to enter following material values dependent on the calculation standard (you select the standard using the Method of Strength Calculation drop-down menu in the Calculation tab).

• R_e/R_p02 - for Steel according to CSN/DIN/ISO standards
• R_m - for Cast-iron according to CSN/DIN/ISO standards
• VHV - according to CSN/DIN/ISO standards
• JHV - for ANSI/AGMA 2001-D04:2005 standard

Narrow the material selection

When you search for desired material, you can narrow the search for desired material. You can search for specific standard or density value. In the appropriate column, enter desired text for searched material property in the "Enter text here" edit field. For example, enter DIN in the "Enter text here" edit field in the Standard column. Only DIN materials are displayed.

Note: The edit fields are case sensitive. Type "DIN" when searching for DIN standard materials, not "din".

Use the Material database to select a part material or add, edit, or remove the selected material data. Double-click the edit field to change or enter values.

Use the first edit field as a filter. According to the specified criteria the list of materials is displayed. For example, if you write "steel" in the Material edit field, only steel materials are displayed. A check box displays next to the filter edit field. Clear the check box to cancel filter selecting and display complete list of materials.

Note: Material database is not connected to Autodesk Inventor Material Styles Library.

The data from material database are stored in the XML format in ...Design Data\Design Accelerator\Tables\Materials folder.

Use the dialog to enter values of wire diameters and the ultimate tensile strength of the selected material. Double-click the edit field to change values.

According to the specified values of wire diameters and the ultimate tensile strength, generator uses the ultimate tensile strength value if you design a spring of an appropriate wire diameter. For example, you set the wire diameter value in this table to 0,072 and the ultimate tensile strength value to 232692. If you set the wire diameter value in the Design tab to 0,072, generator automatically inserts the ultimate tensile strength value (232692) to the Ultimate Tensile Strength edit field of the Calculation tab.

If generator does not find the ultimate tensile strength value for inserted wire diameter in the table, the value is calculated. Generator finds the closest lower and upper wire diameter values and approximately calculates the ultimate tensile strength.

The data from material database are stored in the XML format in ...Design Data\Design Accelerator\Tables\Materials folder. If you edit the data, tables in XML format are by default stored in ...Design Data\Design Accelerator\Tables\Custom folder.
