Is there a failure criterion/model for brittle spheres?

Submitted by shuo zhao on

failure model

Hi, everyone

I am a student. I am  dealing with a failure problem of brittle spheres. These have a lot of flaws inside.I did some compression tests. Single spheres are crushed by a pair of parallel plates. I got the crush load distribution (in terms of critical contact force). 

My question is:

is there a failure criterion/model which relates to load(critical contact force), Youngs moduli and Poisson ratios of shpere and plates, radius and friction coefficient?

Can anybody help me on AUTODYN subroutine?

failure model

When I implement failure model into AUTODYN by user subroutine, I fonud there are some differences between  results come from subroutine and  the results computed by AUTODYN'S provided material model. Is there anybody who is kind enough and familiar with AUTODYN's user subroutine to help me? If possible, an example of a failure model(for example, Johnson-Cook failure model) is highly appreciated.
