![]() | Guilkey, James Edward; Berzins, Martin | Examination and analysis of implementation choices within the material point method (MPM) | The Material Point Method (MPM) has shown itself to be a powerful tool in the simulation of large deformation problems, especially those involving complex geometries and contact where typical finite element type methods frequently fail. While these large complex problems lead to some impressive si... | GIMP; Meshfree methods; Meshless methods; Particle methods; Smoothed particle hydrodynamics; Quadrature | 2008 |

![]() | Guilkey, James Edward | Improved contact algorithm for the material point method and application to stress propagation in granular material | Contact between deformable bodies is a difficult problem in the analysis of engineering systems. A new approach to contact has been implemented using the Material Point Method for solid mechanics, Bardenhagen, Brackbill, and Sulsky (2000a). Here two improvements to the algorithm are described. The f... | Contact algorithm; Material point method; Wave propagation; Granular material; Solid mechanics | 2001 |

![]() | Guilkey, James Edward | Improved velocity projection for the Material Point Method | The standard velocity projection scheme for the Material Point Method (MPM) and a typical form of the GIMP Method are examined. It is demonstrated that the fidelity of information transfer from a particle representation to the computational grid is strongly dependent on particle density and locati... | Material Point Method; GIMP Method; Meshless methods; Velocity projection; Solid mechanics | 2007 |
