How to model highly compact particulate reinforced composite
Тәжірибелік нұсқаулар және стиль
This videos shows how to model highly compact particulate reinforced composite. The model is carried out in ABAQUS using the principle of RVE modelling. The test composite considered here is Aluminium Silicate (AlSiC) particulate composite with an overall volume fraction of 60%. The highly compact particulate reinforced composite is modelled by considering two inclusion sizes of the silica particle to ensure high compaction of the composite.
The inclusion is modelled as an isotropic material while the aluminium matrix is modelled using the Johnson-cook plasticity model with Johnson-cook damage. The analysis is a dynamic explicit simulation with periodic boundary conditions (PBC) implemented. The automatic implementation of the PBC was carried out using the bespoke software developed by CM Videos called PBCGen2D which automatically imposes PBCs on 2D rectangular domains.
Analysis was a tensile deformation. The results were reviewed and plotted in form of stress-strain plots to extract effective properties of Young's Modulus and Strength. #cmvideos #abaqustutorial #rve #composites #pbcgenlite #pbcgen2d #montcarlgen #periodicboundarycondition

Hello, Dr Okereke! So many thanks again for this precious one. A kind request to you please make a video on this paper "Multiscale finite element analyses on mechanical properties of graphene-reinforced composites, Zhangxin Guo, Lubin Song, Gin Boay Chai, Zhonggui Li, Yongcun Li & Zhihua Wang"

Hello @Ark blue, thanks for your interest in the channel and you kind comments. I have looked at the paper you highlighted for modelling of graphene-composites. It does look interesting. RVE modelling of graphene-composites is in my to-do list over the next few weeks. I am working on some other projects but will get to this sometime in future. Thanks.
Hi Dr Okereke, this video is useful and educating as your previous videos, so Thank you a lot. Meanwhile, I have a question Sir; did you have time to check the reference article I mentioned before? I am really waiting for the results of that modelling.

Hello Sina, thanks for your query. I have seen the article and can see what the authors are doing with the modelling. I am not at a position to do this modelling. It is interesting but does not fit within the content of videos that I am focusing on at the moment. Thanks.

Thanks again. Do you have PBCGEN for 3D RVES?

Hello Jide, thanks again for dropping by. No, I do not have PBCGen3D for 3D RVEs ready yet for general distribution. I am working on it and when it is ready, it will be available for people to use.
Hello, thank you for your useful video, if the particles were packaged (as a packing), can we use this method?
@MichaelOkereke

Hello @R. Sadeghpour, of course yes you can! Obviously, you will need to find a way to generate the particles as a packing (clustered particles). The code I used can generate moderate clusters but not excessively high volume fraction packing. The simple answer is yes!
