Simulation requirements<br />
• Hypervelocity impact: Grand challenge in<br />
scientific computing p g<br />
• Main simulation requirements:<br />
– Hypersonic dynamics, high-energy density (HED)<br />
– Multiphase flows (solid, fluid, gas, plasma)<br />
– Free boundaries + contact<br />
– Fracture Fracture, fragmentation, fragmentation perforation<br />
– Complex material phenomena:<br />
• HED/extreme conditions<br />
• Ionization, excited states, plasma<br />
• Multiphase equation of state, transport<br />
• Viscoplasticity, p y, thermomechanical coupling p g<br />
• Brittle/ductile fracture, fragmentation...<br />
