What is Shock Physics?
Shock Physics is the study of material behavior in continuum mechanics regimes where strong shocks, large material deformations, and high strain rates occur. Such phenomena exist in the study of hypervelocity impacts, fracture and fragmentation, vaporization, and high explosive detonation. Shock physics tools (colloquially known as hydrocodes) are primarily developed by the Department of Energy, and have been used in the design of weapons for nearly 60 years. These tools are used throughout the weapons development community and require large computational resource.


Corvid’s Advantage
At Corvid, our researchers combine:

  • Expertise in theoretical shock physics analyses
  • The ability to conduct and correlate appropriate experiments
  • In-house super-computing systems to conduct large-scale (30 to 50 million element) full-3D hydrocode calculations.
Our researchers apply hydrocodes as tools to develop and assess the lethality of a variety of weapons systems and their components. We have expertise in experimental design and interpretation, material, equation of state and constitutive model development. Our experienced and internationally recognized subject matter experts in hydrocode analysis are capable of leading weapon programs from inception to procurement.
