Application of a particle-in-cell method to solid mechanics

摘要: Abstract An extension to solid mechanics of the FLIP particle-in-cell method is presented. The uses two representations continuum, one based on a collection material points and other computational grid. are followed throughout deformation provide Lagrangian description that not subject mesh tangling. This feature permits constitutive equations with history-dependent variables be applied at these no requirement for mapping history parameters from point another. A grid, which can held fixed or adapted as need arises, used determine spatial gradients. Since grid an updated frame, nonlinear convection term associated Eulerian formulations does appear. With use maps between advantages both schemes utilized. No-slip impact bodies, inelastic, elastic, rigid, handled automatically by without resorting special contact algorithm.
