Simulation of dislocation evolution in microparticle impacts over a wide range of impact velocities

The dynamic loading environment created by high velocity microparticle impacts is very difficult to model. The extremely high strain rates, large deformations, and high temperatures affect the flow stress of the material in ways that standard flow stress models cannot capture. Plastic deformation an...
