Hydrocodes are used to simulate large deformation material response and dynamic processes and to solve the continuum equations for the nonlinear response of materials and structures.
Hydrocodes routinely used are based on methods such as:
- One-dimensional Lagrangian to fully three-dimensional Lagrangian
- Eulerian methods to Arbitrary Lagrangian Eulerian (ALE)
- Smooth particle hydrodynamics (SPH)
Expertise in constitutive modeling, fracture mechanics, algorithms, and parallel computing are employed to enhance problem solving. Southwest Research Institute (SwRI) Engineering Dynamics staff enhance and apply hydrocodes to a broad range of problems such as:
- Penetration mechanics
- Fracture mechanics
- Fluid-structure interaction
- Armor system design
- Detonation analysis
- Blast analysis
A suite of codes for these applications is maintained.
