... impacts using two constitutive equations, namely, Johnson–Cook and ZerilliArmstrong. We show that the titanium microparticles experience strain rates in the range of 10 6 –10 10 s −1 upon impact. We evaluate the capability of the Johnson–Cook and ZerilliArmstrong equations in predicting the deformation...
