Very grateful! My dissertation in the final year is about aluminium aramid laminate. Actually I am still a beginner so I always confused about the model of the 2D plain woven aramid by only Abaqus. Relevant three videos help me a lot! I expect more videos about textile composite material model details in the future! Thank you Dr. Michael! Good luck!
Hello @Yifan, thank you for the kind comments. I am happy that the videos have been certainly useful as you settle into the world of textile composites modelling. Good luck with the research. I will certainly be making more videos about textile composites in future.
Hello Dr, thank you for your videos, they are very helpful in learning the program. I would like to ask about polymer braided composites, how to correctly set the weaving structure and correctly apply the acting forces?
Hello, I am planning on making a video about braided structures sometime in future. These textiles are challenging in themselves and applying the forces and the like can seem daunting. When I am able to, I will like to make the videos that will simplify this and make life easy for students. Please keep watching this space till when these textile composites videos drop. Thanks.
Hi, Dr.Michael, do you know the Bistable structure? I want to make simulation of Bistable structure. but I have many problems. Could you do the simulation of Bistable structure
Very deep understanding, very helpful for me! I am very interested in the 3D orthogonal textile composite meshing work you describe at minute 7. Will there be a follow up tutorial on meshing woven composites that I can follow? Thanks!
Glad it was helpful @Xiaoyu! On meshing, I will consider the request and see if it is something I can make a video about. A lot of time, it is all about trial and error until you get an acceptable mesh. Usually, you just have to keep partitioning the domain, until a feasible mesh is obtained. Alternatively, you can isolate only a smaller RVE which will be easier to mesh rather than this holistic version shown her. I will think about it and maybe make such a video.
@@MichaelOkereke Yes, as you describe, the fabric structure I built contains only one RVE, and I'm thinking about how to mesh better, would hypermesh be a little better?
Hello @Xiaoyu, with the meshing, I suggest you follow the suggestion of partitioning the model as that can help in the first instance. I suggest you keep to a brick or hexahedral element. If that does not work, then you can try the tetrahedral element but do understand the limitations of this choice. Finally, I have heard anecdotally that hypermesh is a stronger meshing tool and might be able to help with this but I have no experience of this. What I know is that there are a lot of ongoing research on how to develop robust meshing algorithms for such microstructures as the woven textile composites but like everything else, those research will not be available for public use (in FE solvers) till sometime in future.
Hello @Johnson, you are right, PBC in Textile composite's RVE, can be needed and presents its own challenges. I however did not include that here as you can still get a good result from a normal Dirichlet Boundary Condition but PBC will be preferred due to the heterogeneous nature of the RVE.
Thank you Dr. Michael for sharing this video, but can you making some video about Delamination Mode 1 (Opening) on the Sandiwch Plate or Composite with Numerical and Simulation ?

Hi sir can please make a video on steel .which is Directionally distributed in parallel Direction and perpendicular distribution in Abaqus

Hello @C P, I do not have any experience with bistable material, so unable to help.Cheers.

Hello Dr, you didn't mention assigning of PBC since you recommended using an RVE; is it not needed? Thank you Sir.
