After creating a new composite in Design Materials, a question appears. What destruction parameters should be used then? After all, the material was synthesized new and it must have its own new data? How to synthesize new fracture parameters for further analysis?
Or is the destruction criterion for the new taken according to the weakest material? For example, matrix. Usually it is a polymer and the grains are steel or stone.

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.

Thanks, but I don't have access to this work. Could you describe to me what the author of this work is doing? Or download this work for me?

I don't have access to it either; this is just an example. You can try a search in Google scholar. Or maybe you can have access to the paper from your academic institution. Check with your librarian.

I managed to get this report. But everything that is said there on the basis of the matrix is very complicated. Could it be easier to get fracture data? Maybe some sort of ratio? Something simple.
