Material Characterization

If your material definition does not meet the requirements for the analysis type selected, you will be required to complete the material characterization.

Add Material

To specify the non-linear data, you must enter it in the order of stress, strain, angle, and temperature. To do so:

Click Material > Add > Add Non-Linear Material.
Key in your data or copy and paste it from an Excel or text file.
Specify the appropriate units for your data.
If you do not have data for each column, you may leave it blank by using consecutive separators.

The data shown in the image below was pasted into the window as follows:

0;0;0;23
17.5;0.0015;0;23
35;0.003;0;23
52.5;0.0046;0;23
70;0.00625;0;23
100;0.0095;0;23
125;0.01275;0;23
150;0.016;0;23
168;0.01925;0;23
180;0.0225;0;23

Note: The Advanced Material Exchange 2015 release only supports data entry at angles of 0, 45, and 90 degrees. Data for each angle must contain between 15 and 50 data points, with at least one point in the elastic range of the material.

Review Material

Click Material > Review > Material Data to review your non-linear data set at any time. In the Thermoplastics material dialog that appears, you can view the material description, mechanical properties, filler properties, stress-strain data, and the mechanical model.

This dialog can also be accessed via Home > Review > Material Data.

If any generic non-linear material data is used, it will appear red in color. Non-linear data that you have entered will appear black in color.

Personal Database

If you commonly use the same materials, you may wish to create a personal database to store the Ramberg-Osgood parameters so you don't have to enter the non-linear stress-strain data each time you work with Advanced Material Exchange. Refer to the Moldflow help for details on creating your own personal database, or refer to the Add Non-Linear Material Data section of the Advanced Material Exchange User's Guide to learn how to use the personal database file provided for you.
