Assign material orientation and properties to RVE of discontinuous fiber composite

In the first video of this series ( • RVE of short random di... ) a python script was developed which can create RVE of short fiber composites. The fiber location, orientation and length were random. The intersection between fibers were checked and prevented in a simple way. In this video material properties are assigned to each fiber by a Python script. Material orientation is also assigned to each fiber based on its angel. Using findAt() command and finding the appropriate datum coordinate system are explained.

🙂 Thanks Sir. Your videos helped me starting the simulation of Carbon nanotube reinforced polyurethane that I am working on. Thanks a lot. I will be always waiting for your videos that I recommend for every student or researcher modelling composites 👍💐

Great Work Sir.

hello :) , thank you for the informative video, could you please show us if we want to assign the material oriantation of a curved surface, and we want to locally change the material at each node, how can we do that via scripting ?

There are two possible methods for it:
First to use cylindrical coordinate system
Second to create your axis based on the coordinate of the material point and coordinate of the center of the curve.
