Our high-fidelity, multi-physics, multi-numerics, hydro-structural solver.

Velodyne is a high-fidelity, multi-physics, multi-numerics, hydro-structural solver used to analyze high strain rate large material deformation events.

 

These include target penetration and blast loading by weapons and the resulting damage to the target material such as penetration, perforation, back face spalling, and debris generation. Velodyne contains a wide range of rate-dependent material constitutive and progressive damage routines as well as equations of state to represent the physical behavior of both solid and fluid materials.

 

In addition, Corvid has implemented several unique features that allow us to move beyond the typical limitations of commercial FEA codes and solve complex, high-rate dynamic problems. These features include Smooth Particle Hydrodynamics (SPH), Element to Particle Conversion, Robust Higher Order Auto-Contact, Multi-phase Equations of State (EOS), Thermal/Structural Coupled Solvers, Coupled Lagrangian/Eulerian (CLE) Solvers, and Reaction Kinetics of Energetic Materials.

 

Initial development of Velodyne focused on the needs of the Missile Defense Agency (MDA) to evaluate interceptor effectiveness and provide post-intercept debris scenes for flight test planning and ballistic missile defense system assessments. Because of its ability to accurately model extreme loading conditions, the use of Velodyne was extended to the tactical and combat vehicles, such as the Mine Resistant Ambush Protected (MRAP) family of vehicles and the Medium Tactical Vehicle Replacement (MTVR) vehicle, to assess military crew survivability against underbody blasts by IED/mine explosions.

 

Corvid has also successfully applied Velodyne to the development of innovative light-weight ballistic protection solutions for large diameter solid rocket motors (SRMs) and other high value DoD assets. Another major effort supported by Velodyne is the Insensitive Munitions (IM) program in assessing the response of large rocket motors to IM stimuli, such as cook-off, bullet/fragment impacts, and sympathetic detonation; the success of which has resulted in the development and effective use of a slow cook-off oven designed to meet the stringent requirements for testing large scale rocket motors under US and international IM compliance regulations.

 

Over the last several years, Velodyne has been extensively anchored to test data, both in-house and externally through other contractors or program offices. These comparisons range from simple phenomenological tests to full system level comparisons, showing the breadth of capabilities within Velodyne. Various phenomena modeled across these comparisons include perforation and penetration, failure and fracture, small and large material deformation, and fluid-structural interaction.

 

MDA has even funded the development of a Velodyne Basis of Confidence document which summarizes the operation and usage of Velodyne within the missile defense community in terms of lethality and post-intercept debris. The use of Velodyne has undergone extensive peer review by MDA and the DOE.
