High order material point method
The material point method (MPM) is a meshfree mixed Lagrangian-Eulerian method which utilizes moving Lagrangian material points that store physical properties of a deforming continuum and a fixed Eulerian finite element mesh to solve the equations of motion for individual time steps. MPM proved to be successful in simulating mechanical problems which involve large deformations of history-depend...
متن کاملSimulating Snow with the Material Point Method
This thesis discusses the research and development steps for the simulation of snow with the Material Point Method (MPM). In order to gain an understanding in the technique and mathematics the MPM was researched in detail. All ten steps of the MPM were implemented using C++. First the method was implemented without the collision and implicit update. Next the body-collision for the particles and...
متن کاملThe Material-Point Method for Granular Materials
A model for granular material is presented that describes both the internal deformation of each granule and the interactions between grains. The model, which is based on the FLIP-Material Point, particle-in-cell method, solves continuum constitutive models for each grain. Interactions between grains are calculated with a contact algorithm that forbids interpenetration, but allows separation and...
متن کاملThe Generalized Interpolation Material Point Method
The Material Point Method (MPM) discrete solution procedure for computational solid mechanics is generalized using a variational form and a Petrov– Galerkin discretization scheme, resulting in a family of methods named the Generalized Interpolation Material Point (GIMP) methods. The generalization permits identification with aspects of other point or node based discrete solution techniques whic...
متن کاملImplicit Dynamics in the Material-Point Method
A time-implicit discretization is derived and validated for the material-point method (MPM). The resulting non-linear, discrete equations are solved using Newton’s method combined with either the conjugate gradient method or the generalized minimum residual method. These Newton-Krylov solvers are implemented in a matrix-free fashion for numerical efficiency. A description of the algorithms and ...
