I'm trying to use ABAQUS-Swiftcomp GUI to obtain homogenised RVE properties. It is my first use, and I'm happy with the ABAQUS interface and processing time, in addtion, matrix construction.
I used RVE method with periodic boundary conditions, Chamis equations (rule of mixture as a ref. point) will give relative results. On the other hand, with Swiftcomp, the results are:
- Consistent with the above methods for E1, but significantly different for E2 and E3 (when using Hex elements);
- Consistent in E2 and E3, but 50% less for E1 (when using Tet elements).
Kindly note that I did not use and special type elements. My RVE is set to be periodic, 3D.
Any advice would be great.
Thank you in advance…
