I'll suggest just that to the people at various North American and European companies who've been designing and making expanding hunting bullets for decades, and who all employ professionals from various engineering disciplines who no doubt could provide such mathematical modeling. Several of those companies and people helped me start my research in how expanding bullets work, and I've participated in various ways in their tests over the years. I am sure they'd welcome your help in "corresponding mathematical modelling," which would lend considerably more credence to their products.
