"Base" ALEGRA

 

  • ALE code -- Arbitrary Lagrangian-Eulerian -- provides flexibility, accuracy and reduced numerical dissipation over pure Eulerian code; modern remeshing technology allows for robust mesh smoothing and control.

  • Jet from Shaped Charge

    Pressure and temperature during formation of jet from shaped charge

  • Hydrodynamic and solid dynamics

  • Models large distortions and strong shock propagation in multiple-materials

  • Finite element code; descendent of PRONTO and uses some CTH Eulerian technology

  • Energy deposition and explosive burn models

  • Geometry -- 2D/3D Cartesian, 2D cylindrical

  •  

    Material Models in ALEGRA:

    Alegra Models
    • Equations of State


    • Elastic-Plastic Models


    • Fracture Models
