The Arbitrary Lagrangian-Eulerian capabilities in ALE3D provide a robust solution for high velocity impact problems while other parts of the simulation can be kept Lagrangian to provide an accurate representation of surfaces and material deformation.

  • Fracture and Fragmentation

    In this simulation, a scored steel plate sitting against a copper buffer is impacted by a copper flyer backed by polycarbonate. The impulse launches the steel plate from the buffer, and the resulting biaxial stretching causes the plate to fracture. The fracture occurs preferentially along the score lines.
