Hello,

If I understand correctly, you created a particle RVE in Material Designer:

Is that correct? If not, please send a screenshot of your composite design.

Currently, Material Designer can not calculate the failure criteria for composites based on the strenghts of each of the constituents. But, you may be able to approximate it yourself. They tried to do it in the following paper:

The best would be to test the composite material directly and then compare with your calculations. If the matrix is the weakess link for a particle RVE, then the matrix may dictate the failure of the composite. Double check your assumptions with experimental data. You may be able to find this data in the litterature.
