This tutorial demonstrates how to use experimental data to calibrate and validate a short fiber composite material model. After the validation, the homogenized material will be exported and used to simulate the structural behavior of a flange made of the validated composite.
The coupon geometry and CT scan with fiber-orientation tensor are based on data found in Fatigue of Textile and Short Fiber Reinforced Composites (Materials Science: Durability and Ageing of Organic Composite Materials Set) by Carvelli, V., Jain, A., and Lomov, S. (2017). The actual data from the source might differ from the one in this tutorial since the intention is to merely provide a step-by-step guide on performing material calibration.
This tutorial uses the injection molding simulation data from the previous version of the tutorial, even though it does not correspond with the same coupon. The purpose of using it is to highlight the importance of comparing CT scan versus injection simulation data, since it is often seen that both do not match, leading to unreasonable results when doing the material calibration.
Note: This tutorial requires using Ansys Material Designer which is only available on Windows.
