Coupled particle-finite element methods have been suggested as an approach to modeling particular impact problems not well suited to simulation with conventional Eulerian, Lagrangian, or particle codes. An alternative hybrid particle-finite element technique has been developed, in which particles ar

โฆ Synopsis
Simulations of three dimensional orbital debris impact problems, using a parallel hybrid particle-finite element code, show good agreement with experiment and good speedup in parallel computation. The simulations included single and multi-plate shields as well as aluminum and composite shielding materials, at an impact velocity of eleven kilometers per second.

An improved hybrid particle-finite element method has been developed for hypervelocity impact simulation. The method combines the general contact-impact capabilities of particle codes with the true Lagrangian kinematics of large strain finite element formulations. Unlike some alternative schemes whi
