Abstract:Finally, we incorporate the STM in a finite element simulation of the Taylor impact of two tantalum specimens. Our simulation predictions mimic the texture and deformation data measured from a powder metallurgy specimen. However, round-corner square rolled (RCSR) specimen simulations over-predict the texture development and do not accurately predict the specimen deformation. We attribute this discrepancy to the elongated crystal morphology in the RCSR specimen which is not represented in our mean-field model.
